Some folks won't tell you the truth about this antenna, but I will. It is a virtual dummy load!
I can't think of any other HF mobile antenna that is less efficient. It even takes a back seat to the ATAS series. It isn't any better on the VHF end either. The coils are wound with #24 wire, and are about the size of your little finger.
Go to my web site, and look under Antennas, Commercial.
