These antennas are the result of years of testing and customer feedback. They are not your standard or light duty antennas sold by other manufactures. This is a heavy duty design, No whimpy element or flimsy tuning here. The sleek, simple built to last for years to come design is shown below. Rover tested at or above highway speeds. Works great for VHF/UHF contests. It's the perfect add on antenna for those who have a high gain directional yagi. Saves on rotator wear !. This antenna can hear/work stations in all directions. Your high gain directional yagi can't do that. For use on CW/SSB as well as Digital modes like FT8. (not intended for AM/FM use). Choose round or square element design, your choice, both work the same. I get asked all the time. which design works better, round or square. Answer: Hours of testing has shown, no one can tell if I'm on a round or square antenna. |
