Broadband vertical antenna
The following notes show the design and construction of a Broadband HF Vertical antenna which does not require a tuner
Triband hf vertical
Ground plane vertical antenna for the 20, 15 and 10m bands
Verticale utilizzando una antenna MFJ-1954 e bobina
The modelled inverted-V antenna is full size and will have a higher efficiency than a shortened horizontal dipole. If we consider a full size 1/4 wavelength
Butternut HF2V Modeling
using a ground-mounted Butternut HF2V for several years now with great success

23cm Yagi Antenna building Finished antenna at 1275 MHz SWR under 1:1.5 at resonant frequency
50 MHz preamp Gain 26dB with the BFG135 Preamps for 144 and 430 MHz, for 50 MHz, the BFG135a is a cheap transistor and in my view rather strong. It is not easily damaged by static discharge or RF power. FG connection
