Channel Master Ultra Mini 4 - 4-Port TV Antenna Distribution Amplifier, 8dB gain, Compatible with Non-Amplified TV Antennas, Cable TV and Internet Modems, Increases Signal Strength, Indoor/Outdoor

I'm a Boomer, so I'm old enough to remember that the promise of cable TV was, "no commercials". Since they haven't lived up to that promise they don't get any of my money. I have a rooftop antenna and its coax cable runs into my utility room where it then splits to 4 locations in the house. I had only a passive 4-way splitter, my signal had really degraded and I was not looking forward to scaling the second story roof to check the antenna, which is only 5 years old. But, even my strongest broadcast signals were only in the 60 -70% quality range and I'd completely lost a number of UHF stations. So, after reading a lot of reviews, I took a shot and bought a "Channel Master 3414 4 Outputs Distribution Amplifier" from Amazon. Choosing it because the reviews and the price, because the power cable was included in that price, where with others it was a separate purchase. I've had it installed for two months now and I could not be happier with it. I live in a major metropolitan broadcast market so with the Channel Master I am now pulling in 40 different stations. All of the VHF stations are now showing 100% signal strength and signal quality and most of the UHF stations are showing the same. Even the very weakest UHF stations, which I couldn't even watch before as they had less that 3% signal quality, are now showing over 50% signal strength and over 30% signal quality, which for a digital transmission still gives you good picture and sound. So, if you want to have great reception from a rooftop antenna that is split and routed to numerous televisions, while telling the cable and satellite folks to take a hike, I highly recommend the "Channel Master 3414 4 Outputs Distribution Amplifier" Don't forget, if you are not going to use all the ports you will need to cap any unused ports with an F Type 75 Ohm Terminator cap or you could have signal loss even with the amplifier. UPDATE June 30, 2014: It's now well over a year since I installed the Channel Master amplifier and it's still doing a bang up job. Recently I had some work done on the house and decided while there were pros up on the ladders to have them replace my 6 year old "airplane" shaped antenna with a new Terrestrial Digital DB8 Multi-Directional 'Bowtie' UHF DTV Antenna. The new antenna is mounted about 5 feet above the roof peak, which is about 20 foot high. Living 8 miles from downtown Chicago the Channel Master/Terrestrial Digital DB8 combination is now pulling in 70 channels and when you discount the duplicates broadcasting on two frequencies, one HD one not and the weaker ones, I have well over 50 strong, viewable, channels. The interesting thing is I get different channels depending on the brand of the TV or converter box. For example with my Toshiba LED TV's tuner I get a series of Channel 13s but not the series of Channel 22s I get with the Zenith converter box in the same room which does not get the 13s. I've actually gotten a little hooked on the subtitled Korean historical costume dramas running on one of the Channel 24s I get. My only regret is I wish I'd put another 5 foot extension on the antenna mast; I think if I had I would probably be able to pull in the Northern Indiana stations around Merrillville, Hammond and Gary. So, I'm still 100% behind my 5 start ratting for the Channel Master.

The Channel Master CM-3410 signal distribution amplifier worked very effectively with my television sets. My home is only about 12 miles from most local TV transmitters, but reception had been problematic because we employ indoor antennas some distance away from our TV sets. Most challenging was a basement TV fed from an antenna by a window at the other end of the room. Only a few channels came in reliably on this TV. Reception on our upstairs TV, also relying on an antenna in a window, was better. For both sets, frequent antenna adjustments were necessary to obtain satisfactory reception. And human movement in a room could cause some images to become pixilated or disappear. The labeling of the terminals on this amplifier can be confusing, because it is tiny and nearly illegible, and its terms may seem ambiguous. (1) On one side of the amplifier is a single terminal, labeled "PWR IN / RF OUT +15db." A coaxial cable goes from this terminal to the TV. (2) Directly opposite this is another terminal, labeled "PWR IN / 12-16VDC 250 mA." A coaxial cable connects this terminal with the DC power converter, which plugs into a regular AC outlet. (3) Next to the power terminal is a third terminal, labeled "RF IN / REV OUT -1dB." For off-air reception, the coaxial cable from the antenna attaches to this terminal. The amplifier comes with a 6-foot coaxial cable to connect the DC power converter to the amplifier. You will need separate coaxial cables to connect the amplifier to the antenna and to the TV. The lengths of the cables needed will vary according to the locations of the antenna, the DC power converter, and the TV. In general, it is best to keep the amplifier as near as possible to the antenna. Just keep in mind that you will need three separate F-Pin to F-Pin coaxial cables, only one of which is included with the amplifier. Both of my TVs are served with RCA digital flat multi-directional antennas, whose built-in 6-foot cables attach to the amplifiers. The basement amplifier is connected to the TV with a 20-foot cable; but only a 6-foot cable was required to connect the other amplifier with the upstairs TV. These antennas did not work very well with 10db gain amplifiers. But with the 15db gain CM-3410 amplifier, the basement TV pulled in all the desired stations--mostly without any adjustment of the antenna. The results were so good that I acquired a second amplifier for the upstairs TV, and it solved nearly all the problems we had been having with it. The effectiveness of this amplifier will depend on your specific situation. (See other reviews.) It may not help to pull in a distant signal via an indoor antenna. But if you are getting poor reception of certain stations, this amplifier may be the solution.

This device is nice and heavy, with screw holes that let you bolt it to something. The screw holes are too small to accommodate standard drywall screws, which is kind of dumb. I have it screwed to a 2x4 in my attic, which is where the HDTV antenna is. The power cord is only 6 ft. long, so look at your setup before you decide. The power cord APPEARS to be just a length of coax, but I sure couldn't swear to it -- I dunno whether one could substitute a longer cable. So I ended up wiring an AC outlet in my attic right near the antenna. But if the cable you want to amplify comes in the house right near an existing AC outlet (hardly a rare setup), this thing will install really, really fast. When I was shopping, it took me a long time to figure out what kind of amplification I was looking for. This device seems to be designed to solve the problems of people who get good reception, but have to overcome splitters or long cable runs; it does NOT appear to be for those trying to compensate for poor reception. I had great HDTV reception, pulling in over 100 DTV channels locally. But there wasn't enough signal to make it to both of my TVs, each of which was at the end of at least 100 ft. of coax cable. Either TV connected directly to the antenna by itself was fine. Both TVs at once was pure death. There appears to be a lot of variation in people's situations with DTV, so it's hard for a reviewer to generalize. But if you have a well-situated AC outlet, and are trying to solve the problem of multiple TVs on long runs of cable, this appears to be a very good option at an easily affordable price.

Excellent product, very easy to use. I had installed an OTA antenna some time back and was able to pick up most stations in my living room just fine, however, in my office I was missing several stations completely. Since they all run off the same antenna and I could get some stations in my office, I found this to be odd. So, I went ahead and purchased this unit along with a "PCT Series PCTMPI1G Power Inserter for Distribution Amplifiers" and had it up and running within a few minutes. Not only was the signal much stronger in my living room, but it was good and strong for all stations in my office also. Still need to run more cables elsewhere, but I'm positive this will handle them just fine. You might ask why I got the "Power Inserter" mentioned above? This box is very well made and weatherproof, so I located it outside under my eaves where I split off antenna signal to my different rooms. However, the power supply that comes with it is made to hook directly in to the box and be plugged in right next to it, but I didn't have a power outlet there. The power inserter allows me to insert the power right before my TV where I do have power and use the same cable to go back to this box. Normally the power alone would go into the top left input shown in the picture, which is clearly marked. When using the power inserter, the bottom left plug is clearly marked as being available for both power and antenna combined. The two work great together. That might be my only complaint is that I was a bit cautious trying to figure out what to use. It's not clearly documented in the descriptions. I was cautious in getting a different brand power inserter for this, had a "Channel Master" version been available on Amazon I would have gone with that. With some research I felt fairly comfortable going this way though. I would have gladly spent a bit more money to get a channel master distribution amp that included the power inserter with it though!!

A little while ago, I went to to install a C4-CJM Clearstream-4 Antenna on my roof. I had successfully tested it indoors on a short cable directly to one TV. I was getting about 30 digital channels. However, once it went on the roof, it needed 100ft of coax cable to get down to my basement. I also put in a TII 212 Lightning Surge Protector to keep my equipment safe. The problem is, this all dropped the signal immensely. Even without a splitter, I was down to about 25 channels, with one of my favorites freezing up every now and then. Yet the whole point of getting it to the basement was because I wanted to split this out to multiple TVs. With a two-way splitter (-2.5db), it was still bearable. I went down to about 22 channels per TV. However, I wanted to split it up to 3 TVs. When I tried hooking up to every source in my house with an 8-way splitter (-12.5db), it was pretty much useless. A 4-way splitter (-7db) was somewhat bearable, but I did still lose a few channels. Furthermore, the channel that froze up every now and then was now freezing every 3 seconds. That's when I decided to go with this amplifier. As opposed to a loss of signal, the Channel Master CM3418 promised 8-way splitting with a 4.5db gain. I went ahead and hooked this up with all 8 sources in my house (3 actually connected to TVs) and fired it up. The results were excellent! I'm back to 30 digital channels, and the one that flickered was coming in clearly on all 3 TVs! As for quality, the equipment seems well made and sturdy. I mounted it within my media box and was sure to hook up a ground wire. It all looks clean and organized. There is an indicator light to show that power is reaching the unit. The system came with a power adapter and a coax cable (about 3' long) to hook it up. Needless to say, I am very pleased. Excellent quality and excellent price.

I started TV antenna project more than a year ago but was stuck with Ladder. I initially ordered Antennas Direct C4 ClearStream4 Outdoor Digital HD TV Antenna. It gives me pretty good reception even just facing window in the room at upstairs but my wife hates to see the huge thing in her cozy office room and I wanted to completely replace all tv connection to timewarner cable to air. The only problem for me was ladder. My two story house is small but tall and I needed a tall ladder which may cost $200-$300 (or more) to reach roof and I wonder if I needed it again after installing antenna. So, this nice antenna collected dust in my garage about a year and finally I decided to hire someone has ladder and experience which costs me $150 for labor and guarantees the result (save me from the risk to climb up to the roof). Installation seems pretty straightforward with just one additional cheap mounting kit (Skywalker SKY32812) and a 3' long strong pipe I bought from home depot. I actually asked him to install this antenna by side of the roof since the pipe is long enough. It's same place with satellite antennas installed on every other house's roof in my community. I didn't want to get in trouble with HOA. I returned to my living room, removed cable service connection, hooked up this and there's no channel scanned at all! It turns out the closest room to the distribution center in my house has some reception but not as strong as direct connection to the antenna. I decided to buy an amplifier since the cabling in my house seems too long which might cause high impedance and ordered Channel Master CM3414 Distribution Amplifier. It was painful to wait another week for it's delivery but worthy! After getting the amplifier and replacing the old distributor with this, I could get 80 free digital channels in all three rooms of my home! It's amazing since I could just get less than 30 channels even with direct connection to antenna when it stood up facing window in the room upstairs. Sometimes, few channels cause trouble for a moment by certain weather condition but I'm totally satisfied with this. As others said, some HD channels are even clearer than timewarner cable. I just disconnected timewarner and subscribed AT&T DSL internet only service which saves me more than $35 per month. (Timewarner's basic broadcasting programming is now $22/mo and internet basic is $42/mo which is crazy) I heard ppl lives in urban area can get 100~200 free digital channels just by installing this kind of antenna on their rooftop. So, I strongly recommend anyone else this amplifier with rooftop antenna!

I live in a semi-fringe area 40 miles from the TV transmitters. Most of the channels that I regularly watch over the air play fine, but recordings on my DVR usually start with a warning that the signal is weak and the video quality may be poor. One channel is iffy some of the time, and in the last month has gotten unwatchable. I bought the amplifier in the hopes of improving everything, but especially that one week channel. I carefully installed it according to the directions, it's pretty simple. It made no improvement in my reception. I emailed Channel Master and asked for technical support. I got an email back with instructions, followed by a phone call the next day! Joe was knowledgeable, friendly, and helpful. He looked up the antenna I'm using, and he looked at reception strength for my address and concluded that I really needed a better antenna. He said I could try moving the amplifier to the antenna mast so that it was within 3 ft of the antenna. If that didn't work, then he suggested a much better antenna and also an upgraded amplifier. I tried moving the amplifier close to the antenna, but it still didn't make any difference whether it's in the circuit and working or whether it is taken out and I'm just running the straight antenna into my tv. I'm electing to get the upgraded antenna that he suggested and also an upgraded amplifier. Total cost of those two would be $215, compared with about $115 for the original GE antenna and basic Channel Master amplifier. It is possible that the amplifier I got is defective. Joe didn't seem to suspect that, but I didn't bring it up either. I decided instead of getting a replacement I would just upgrade to the next level of amplifier. The good thing here is that if I can get a good picture without the amplifier I can return that for a refund. Likewise, if my old, smaller antenna works well with the better amplifier, I can return the larger antenna. In short, I will have the opportunity of trying the combination that gives me the best reception at the best cost. I was very impressed with Channel Master's customer service. Having just spent an inordinate amount of time trying to contact Google about an unexplained charge on my credit card, and having spent two years arguing with Comcast about bad service. It is a joy to run into a company that takes customer service seriously. Channel Master is the best. Update: the larger antenna and powered amplifier produce rock stable reception on all but one channel. After numerous tinkering and tech support calls with Channel Master, I finally called the weak station. They are limited by the FCC and unable to produce a stronger signal, and it's on VHF rather than UHF. The bottom line is there is nothing to be done short of getting a deep fringe antenna. In short, Channel Master provided good support and good product. I will sort out the best combination of equipment for my location. The problem channel is going to have to remain aproblem so long as heat and humidity are high in Tennessee! Hmm October.

TOP NOTCH... I installed a new Element roof antenna and the Channel Master Ultra Mini 4 amplifier... It works great... I picked up more channels then we had before on 4 tv sets..... After installing we picked up over 50 channels.

Tengo el servicio básico de televisión por cable y suele llegar débil la señal de los canales, y siempre se ven con estática o como si se encimara un canal sobre otro (se ven imágenes opacas de un canal en otro canal), por ello decidí comprar este amplificador de señal y realmente mejoro la calidad de la señal, ahora se ve sin la estática y sin imágenes encimadas, sin embargo, para que funcione el Amplificador se debe mantener todo el tiempo conectado a la luz eléctrica porque si se desconecta la señal se ve mal y con mucha estática pero cuando se conecta se ve muy bien, ademas no afecta el servicio de Internet por el contrario parece ser que ligeramente lo mejora un poco (el servicio de Internet es por cable). Si tienes interés en mejorar tu señal de televisión sin afectar tu Internet por cable considera comprar este producto, porque realmente es útil y funcional como Amplificador. Ventajas: -Mejora la Señal de Televisión (la Amplifica y se ve mejor la imagen del canal) -No hay perdida en la señal de Televisión o Internet por cable y ligeramente mejora esta ultima un poco (No es un divisor/splitter por lo que no disminuye la señal) -Es fácil de Instalar, tan solo se conecta un cable coaxial a un regulador de voltaje que el mismo producto trae, y después solo se conectan los cables al amplificador y a la luz para que el aparato funcione (trae un manual donde se muestran las conexiones, sin embargo recomiendo ver tutoriales por Internet para una mejor comprensión de su uso). -Tiene 4 salidas para la señal (Solo he usado 2; una para el cablemodem que es el internet y otra para la señal de televisión y ambas funcionan correctamente) - No se calienta en exceso, el Amplificador lo he utilizado dos días seguidos y su temperatura es lo que podría considerarse como normal (se siente tibio) Desventajas -Si el Amplificador esta desconectado de la corriente eléctrica la señal se ve con mas estática (Si no conectas el Aparato a la corriente electrica y lo quieres usar sin luz como si fuera un divisor de señal no te servirá, porque la imagen se ve mal) -Si se va la luz el Aparato no mejorara la señal, solo pasará una imagen de los canales al televisor con estática (Sin embargo si se va la luz tampoco funcionará la televisión) -Es un Aparato algo caro. -Necesita estar conectado a la luz eléctrica, o si - no la señal de Televisión no se observará bien.

I was getting 15 OTA channels (using a single ClearStream 2V) in Hamilton, Canada using a 4 way unamplified splitter. Added a LNA-200 pre amp and got 20 channels with a 4 way splitter being used. If I hooked the antenna direct to 1 tv (no splitter) I got 30 channels so I bought this CM-3414 dist amplifier to use with the preamp. Hooked the 4 way back up and now have 30 channels. A few Buffalo channels (2.1, 2.2, 2.3, 2.4) are on the edge but I point the antenna between Buffalo and Toronto (prevents potential over amplification issues but to be honest, it did not seem to be a problem with this setup) and it still pulls in Buffalo channels. Satellite dish has been removed ! May get a longer range antenna but cannot complain given how cheap this system is and the number of channels. CM-3414 is a great product but I may have been better off hooking up 2 tvs and using a 2 way splitter to get the '2 channels'. Channel 2.1, 2.2, 2.3, 2.4 had absolutely no picture with an unamplified 4 way splitter (signal strength below 20%) so this dist amplifier definitely is worth the money. It is also well constructed with great connectors and I like how it is powered through a coax cable (it even comes with one).

I used this for boosting a digital cable signal for a Vecoax device... the signal was in the 700ish mhz range and it worked great. In the end you should remove all unnecessary splitters and/or couplers if at all possible. Cheap splitters may not even work at the correct freq and they are just passive devices. This is an active device and can boost the signal up to 10x... If in doubt, order 2 of them in case you need a little extra signal on a long run.

I am using it to boost then YOU Broadband RF cable signal before installation my broadband internet connection was very bad and use to get disconnected frequently cable modem hated specifically near the RF cable connector. On installing this product now I get 4 to 5 mbps uplink and downlink speed and no disconnection problem and no cable modem hating problem.

When I first installed my OTA antenna, I already had the signal going to two TVs and got reception of 37 channels. According to TVFool, I got all the nearby signals that I was aiming for (CN Tower and Buffalo broadcasts), but not two Hamilton stations. When I split this into three TVs, I lost most of the Buffalo stations due to weakened signals. To resolve this issue, I got the 4-way distribution amplifier from Channel Master and hooked up the three TVs, leaving the fourth port unused (on a side note, I am using the pre-existing coax setup from my long-ago cable TV provider housed in an outside plastic case to pull in the OTA signal). The net result of this was that I got all of my stations back, and I got the two Hamilton stations too! So the Hamilton stations were likely too weak when I split it into two, but were restored when I used the distribution amplifier. The amplifier itself is sturdy and heavy with a smooth painted finish, so it would last even if it were completely exposed to the elements. I love that the input power is provided through a coax cable because you can use your existing coax cable installation to provide power to the unit without running another power cord into your box. I simply plugged the wall wart near one of my unused TV jacks, used a short coax cable to connect the wall wart to the jack, then connected the other end of the corresponding coax line to the power input of the unit. Very easy and I didn't have to use one of my outdoor AC outlets to power the unit. Just make sure that the power-providing coax line is completely isolated and is not connected (via splitter) to any other cables, then test the voltage (~13V DC) of the other end of the power coax cable before you screw it into the unit.
