Ultra Mini 8 - 8-Port TV Antenna Distribution Amplifier, 4.5dB gain, Compatible with Non-Amplified TV Antennas, Cable TV and Internet Modems, Increases Signal Strength, Indoor/Outdoor

It deserves 6 stars. Great rugged piece of equipment. Channel Master makes some good gear. I could tell the quality by the short cable they included for powering the unit, which is the highest quality. Easy to install, works great. Has power indicators on both the power supply and the distributor unit. Recommend.!

This device seems very solid and has performed well, distributing signal to 7 TVs in my home.

Needed this to set up an antenna. Signal was adequate and provided enough power to pull the news during hurricanes when running off a generator. Just screw in and plug in - easy to use and did a great job.

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.

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 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.

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.

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.

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).
