MLA-30 Loop Antenna Active Receiving Antenna 100kHz - 30MHz for Short Wave Radio

Bought this in May of 25. I am a SWL listener, I just listen to Ham operators. I have an old Hammarlund 170 receiver. This antenna operates like $200 antenna. Those who have this or about to get one cut the 33 feet RG316 off too about 5 feet near the MLA-30 antenna box. then buy RG8X 50 ohm coax to you receiver. Of course do this before to put up the antenna. Much better noise reduction and reception. Also, add some ferrite ring cores around the cable especially at the connect of your receiver and out of the MLA-30 box. I have my loop about 21 feet off the ground using 3/4" EMT conduit. I also drove an 8ft copper ground rod in the ground for adding gas lightening protection. I also grounded my antenna 3/4" EMT mast to the ground rod. As of this writing Amazon has this antenna unavailable? But they do have the MLA-30 plus.

Received the hoped for plus model. Usable as supplied with the small wire loop but does not compare well with a half wave wire antenna. Increasing the diameter of the loop to about 1.3 meters using wire and supports I supplied made a significant improvement in signal to noise ratios. At this size and choosing a location away from the house improved reception of shortwave and am broadcast better than the 40 efhw used for comparison. Nulls were observed as the antenna is turned as expected. I bought this primarily to lower noise levels on the 40 meter ham band. I'm pleasantly surprised with the good result.

I am surrounded by large trees that of course interfere with performance but it's still good

Works great

I live in town and the ability of my radio equipment to receive and hear stations has always been severely hampered by all sorts of local RFI so I started looking into the Amateur radio promised land of loop antennas to solve my problem. My first step in the process was to browse the various loop antenna kits sold by companies such as MFJ, etc. I found all of those choices cost hundreds more than I was willing to spend. Then I came across this very reasonably priced active shortwave listening antenna kit on Amazon . The kit comes with everything you need except for a SMA female to PL259 male adapter that you will need for plugging it into your ham radio receiver and a 5v power source for the antenna pre-amp. You will also need to build a frame to hold the antenna and accompanying hardware. I had a lot of fun over a weekend putting together my antenna frame and was able to customize it the way I wanted for an indoor installation. So with the frame built and the antenna assembled and connected to my radio, I fired it up and like magic my previously almost deaf radio rewarded me with a 40 meter band full of wonderful loud and clear QSOs. It was an awesome moment and I was able to enjoy these results with the antenna setting on a tripod in my attic. My final thoughts about the ML-30 are as long as you don't need a loop antenna for transmitting signals you won't find a better value than this inexpensive active loop antenna kit. With this kit you will be able to build a nice fixed location or portable low noise SWL loop antenna without having to spend hundreds of dollars. I'm happy with my results using the antenna kit and I would buy it again.

bought this a while back but life gets in the way and I didn't start using it until last week. I've been mostly looking at broadcast bands ranging from 5 to 16Mhz and I've been picking up stations as far as Japan and maybe further, hard to tell when you don't recognize the language. and while you get the best reception at night I'm still getting some stations during the day just not as many. assembly could not have been easier, I used an old broomstick and with a hand saw cut a slit on one end and hung the loop from there, then used on of the included screws to secure the box to the stick when the loop looked fairly round. ran the coax to the included rf filter/amp and then to my SDR radio. I had previously been using just a extendable antenna with poor results and wondered if it was my cheap SDR, this antenna made a world of difference. I duct taped the antenna to a dolly handle just to get it some height off the ground and so it wouldn't fall over.

I compared this to my attic dipole. My dipole was less noisy and had stronger reception. This is not robust, forget about mounting it outside unless you fortify it. Amplifies all the white noise too as well as modulation; this is directional so you constantly have to find your sweet spots per station and keep turning it until noise goes away, and yes, it is a 30+. I contacted seller to try and get an answer if it ships as a 30+ or not - they ignored me. Have fun SWL.

Played with a yoyager pro for years, then with the information control hitting the internet I upgraded to a Tecsun PL880. This worked well, cept this annoying humm was always in the background. We live on a hill right next to the city limits, and RF interference was the likely cause. No before this mag-loop I might get 2-5 channels before dark, maybe 5-8 afterdark. This numbers on the telescopic or clothesline antenna. So I have this 20' away from my cabin, on a PVC pole atop an RCA Rotor, and WOW what a difference so far!!!! It's 3hrs till dusk & I have a dozen VERY CLEAR channels coming in!!! Best Damn SW Listening Ever!!!! Can't wait for night :D
