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 →
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
