Antenna Vertical Links →
Dipole vertical demi-onde
At a height of lambda / 4 from the ground, the radiation pattern is close to that of a vertical quarter wave on a ground plane, with a starting angle of about 15 degrees on the horizon, favorable to the DX
Half-wave vertical dipole 14 MHz
building a half wave antenna for 20m radiator I took 10 meter wire, 2.5 mm thick
Effective HF Mobile Antennas
One of the problems with HF mobile operation, especially on 160, 80 or 40 Meters is antenna efficiency. The problem has been addressed in numerous publications for years
Groundplane antenna
This is the antenna I have found to be the most effective limited space radiator that I have ever used

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
