Double Zepp The Double Zepp (Doublet) antenna is a classical antenna in our series of HS4 Legendary Multiband Wire Antennas. It covers 7 bands, 10-12-15-17-20-40-80m. Unlike typical antennas, this is a non-resonant antenna. The performance characteristics are quite outstanding. The antenna consists of symmetrical horizontal radiating e...

Cardioid (80m) The Cardioid Pattern antenna is designed using a two element vertical phased array architectecture. A pair of 5/8 wavelength radiating elements are driven with an optimised phase difference to produce the cardioid pattern. This antenna has its own counterpoise system and has been modeled over an excellent quality ground ...
