20m 1/4 wave vertical The 20m 1/4 wave vertical, when installed over a good ground structure, will outperform a 1 /2 wave dipole at 1/4 wave above ground for radiation angles less than 30 degrees. Even a shortened loaded vertical similarly installed, will still outperform 1/ 2 wave dipole at heights lower than 1/4 wave for radiation ...

4-square array monopoles for 80m, very good ground Four Vertical Arrays (The Four Square) Four vertical monopoles are arranged in a square and separated by a quarter wavelength. The antennas can be fed in a number of ways. Generally the front antenna is fed at 180 degrees in relation to the rear antenna, and the two side antennas ar...

4-square array monopoles for 40m, very good ground. Four Vertical Arrays (The Four Square) Four vertical monopoles are arranged in a square and separated by a quarter wavelength. The antennas can be fed in a number of ways. Generally the front antenna is fed at 180 degrees in relation to the rear antenna, and the two side antennas a...

H-Quad Loop (10-80m) will tune and work for 10/15/20/40/80 meters.!!! This ant. is ONLY for standard Ham Bands, NO Warc Bands and 11 meter Band.!!!! These Omnidirectional antennas offer Horizontal polarization, and about 2.1 dbd of gain. They are much quieter than a dipole or a vertical, have a broader bandwidth and will usuall...

Equilateral Delta Loop for 40m with 30ft base height, very good ground THE DELTA LOOP IS A MONOBAND ANTENNA Although the vertical-plane delta loop either pointed up or down and fed virtually anywhere will radiate well enough to provide contacts, it is a relatively poor performer in any configuration when stretched to other bands, c...

Lazy-H wire antenna, multi-band for 10, 15, 20 and 40m, 88ft x 44ft, 95ft above average ground The LAZY "H" antenna is a general type of antenna that is in the curtain array family. By placing TWO 1 wavelength dipoles in a plane that is at right angles to the direction of maximum radiation and keeping the proper in-phase curr...
