    I bought mine several years ago at the Orlando Hamcation and would buy it again. It works as advertised and although I love my Wolf River Coil vertical, this antenna outperforms the WRC probably due to the height. I have it configured as an end fed “L” in a 35 foot tree. I’ve worked the world with 75 watts. Easy up. Easy down. Love it.

    I bought this antenna because I live in an HOA restricted area. I bought a self tapping screw hook from the hardware store for a dollar and some change and hung this antenna up. I purchased the 66 ft version and the 130 ft version. I also purchased the line isolator. The first contacts were DX. Worked all of Europe the first night. When I turned on my radio and heard nothing I thought it was the antenna, and it was, the antenna is so quiet that I had to turn on both preamps to hear noise. Everyone else was hearing static and noise at a level 4 or 5 and mine was non existent. I grounded the antenna to a 32inch ground spike that I purchased online and that is to bleed off static. The 66ft end goes into a tree. My internal radio tuner is not needed, however I use it so the radio sees 1:1. But on 10-40 and even 6, this antenna tunes with the internal tuner. It will not tune on 60, 80, but it will tune on 160. I’m not so certain that it will work well on 6 or 160 but it does tune with the internal tuner. He advertises 10-40 and that is where it works very well. Got thru pileups with 100 watts. I don’t use amps, just my radio and antenna. If you want something that will work as advertised, then this is your antenna. Don’t compromise your system with antennas that are non-resonant. This antenna is surely resonant. I hooked up the rigexperts and flawless results.
