  1. William Stoops –

    Nice construction and works as advertised, every item I have purchased from My Antennas has been great. I now have the 9:1/4:1 UNUN the 75-10 49:1 end fed the 80-10 49:1 end fed, and the CMC-154-3K 1-54MHz common mode choke and am very satisfied with all.

    At first I was perplexed. I just could not seem to get it to work. Once I bonded the balun to the tower I was pretty impressed. As usual any antenna work equals dead bands.
    Over time I was able to tweak the length and now have it almost flat across most of my favorite bands. I can not comment on 160m. But everything except 6m I have had excellent comments and reports on. 6m I have a large J pole and 10m I have a radial.
    Right now I have a slopper. balun at 50′ running out 84′ to a 15′ post in the ground. balun is bonded to the tower. About to add a post and another 100′ of 12 awg wire. YOU MUST GROUND THESE or they don’t work.
    All in all I would give it 5 stars. Excellent construction. Good materials and performance. Very happy and makes the Mrs very happy. I have to listen quite a bit about my colleges antenna farms. KC3SNR 73

    Great UNUN. I’ve tried a few from other companies but they had a tendency to fluctuate my SWR readings even though they were supposedly rated for higher wattage than what I was using. This MyAntennas 9:1 & 4:1 has been working flawlessly for over a year now. It is in use every day for hours on end and I’ve experimented with changing the wire, length, and configuration and it works like a champ from 160m-6m. Great item and will probably purchase this or a similar one soon for another antenna project.
