Butternut HF2V Modeling


I started by modeling the basic (80m, 40m) antenna; below are some results from MMANA assuming an antenna length of 10m

Antenna Vertical Links

200



Antenne verticale ground plane a radians inclines
The radiating element is a vertical quarter wave surmounting an artificial ground plane consisting of four radians of length lambda / 4 inclined

Antenne verticale raccourcie 40-80mt
The radiant part of the antenna consists of a telescopic shaft with tie rods. The capacitive cap is not finished and the resonance is still at high bit

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
