A freestanding tower in a vertical antenna
It may be interesting to use a high tower supporting other antennas as a vertical antenna. The subject is very vast

Antenne verticale raccourcie pour le 14 et 28 MHz
Antennas of this type, to have a high efficiency, all needed an excellent grounding or a counter weight in the form of radians
Antenna verticale per hf non accordata
Elettricamente si tratta di una 5/8 per la gamma CB, dunque e' utilizzabile cosi' com'e sia in 27 sia in 10 metri, accorciandola leggermente
Antenne verticale 5/8 de lambda
Compared to the lambda / 4 antenna the 5/8 antenna has a gain of about 3dB, which is not negligible for an omnidirectional antenna

50MHz to 28MHz RX Converter The concept of the rx converter is quite simple and nothing really new. the local oscillator is a standard colpitts crystal oscillator producing the 22mhz lo signal
