K-180WLA Active Loop Broadband Receiving Antenna 100kHz-180MHz 20dBi SDR Radio Small Loop Short Wave Antenna,10-Meter Feeder（TNC to SMA）& USB Supply

I got this for myself to test out, on my portable SDR receivers. The K-180WLA is a phenomenal antenna once tuned correctly to your receiver, It will pick up a lot of stations. I tested out K-180WLA on LW, MW, FM, 41 meters. The K-180WLA impressed me, I am very particular about antennas and the wires that come with them. Check out the videos of my testing, I was using a stylus that has been around the block and I need a need to get a one, new hence the pressing issues I was encountering on my videos The antenna as you will see picks up a lot of strong signals the scope will show and reflect what is being broadcasted Including the strongest signal. The K-180WLA loop antenna components amplifier, antenna, waterproof housing are made extremely well you can clearly see they put a lot of into the K-180WLA excellent work. Right below the loop there are 4 screws you on the box you can open up an and inside there’s a switch inside for FMDX and HFDX with a very well made gasket to not let water inside making it great for a permanent outdoor solution. I recommended the K-180WLA to all of my HAM, shortwave listeners. They ended up buying the antennas as soon as I got off the phone with them. They were having a lot of noise interference issues for shortwave LW MW. This was due to the amount of LED street lights and cameras they are running for their home that throw out a lot of dirty signal and interference. I had the same issue this antenna solved the problem in a hitch…. Now battery life is excellent from my testing. Battery voltage is consistent. Great idea for a portable solution and have several small cases of extra batteries if your backpack while your other ones charge up on a battery charger using a good battery bank. A set of batteries come installed in the amplifier to get you started listening. My takeaways: Excellent having issues hearing stations in noisy environments this is your solution. The stability value for the money ease of use , cable length. It’s compatible with a lot of different SDR radios and shortwave radios I have tested with excellent results with K-180WLA Read the manual for proper installation the manual is easy to navigate the fact the manufacturer included photos of how to set it up correctly to make it easier for customers is awesome. Take and your time and put the antenna together piece by piece. Connect everything and start listening. *Use PVC glue only* Once you have it set up to your liking. You can get PVC glue right on Amazon. Buy it I promise you will not regret it happy listening 📻

I've been using this for several days and it is exceeding expectations. I am using it indoors. I live in a very high noise, city environment. This is now allowing me to receive stations I could not hear before. It has brought back joy to shortwave and mediumwave listening for me. I cannot recommend this antenna enough, especially for extremely noisy environments.

The amplifier module has a rechargeable battery, which is really nice for use in the backyard or while camping. Not "hard" to set up, but takes a bit of manual dexterity to mount the loop to the antenna box, as the washers and wing nuts like to "fly off" due to the steel loop's "memory" of being squashed in the bag/box. Once you get the loop on the mounts, it stays firmly attached. LOVE the ease-of-use. Turn it on, and tune your receiver to whatever HF frequencies you want! (I used mine exclusively for <30 MHz, so can only comment on this range.) Since a loop antenna is inherently directional, you can turn it to enhance the reception of a desired signal, or null out a remote noise source. (I used this capability to map out the noise sources in a park, and identify the best places to raise an HF vertical antenna, to avoid them!) I also used this receive-only loop antenna with my RTL-SDR (and other) software defined radios, and it works exceptionally well for its size. I would buy another one of these in a heartbeat!

I had been using a passive dipole antenna on my SDR with very poor results. At the recommendation of some buddies, I tried the MLA-30+ active loop antenna. I simply taped the antenna to the window in my office, connected it to a dongle SDR and I am picking up stations o 10 MHz over much of the Eastern third of the US. Of course it is not as food as a full sized antenna, but for a quick indoor installation it is quite good!

Best overall antenna for SDR 300 khz - 165 MHz in terms of cost vs. performance. Mounts easily on mic/light stand or other stable vertical support.

Junk. Absolute crap. Sorry I purchased it.

Antenna is simple to put up and hopefully will last for a while, I have it on a 10’ mast and it doesn’t do a bad job, performance isn’t great, but brings in some stations pretty decent, good fast service and as described, for the money it’s not too bad

Quick delivery. Great product for the price.

受信感度が良く、BCLに役立ちます。

Great for use indoors. Not portable.
