Verticale per 30/40 m

Ritengo che sia un'antenna estremamente semplice, più complicata da spiegare che da fare i radiali ,sono 6 - 3 per i 30 e 3 per i 40

Antenna Vertical Links

184



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
