Verticale per 30/40 m

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

Verticale per 30/40 m




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

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

Four Band Switched Inductance Vertical, W5TOM
An old transmitter tank coil has been fitted with an Ameritron remote antenna switch mod. RCS-4 to change the taps on the coil to tune 4 bands; 80, 20, 17, 15 meters

Groundplane antenna
This is the antenna I have found to be the most effective limited space radiator that I have ever used
