End fed antenna per i 160m
End-fed antenna un filo e 1/4 d'onda per i 160 metri e cioe lungo 40 metri. Ho costruito un circuito LC di prova, utilizzando una induttanza variabile roller inductor da 140uH e 1 condensatore variabile da 500 pF da 5 kV, piu uno in parallelo del tipo door knob da 500pF 21kV, si trattera poi di leggere i valori di C e di L e quindi di mettere i componenti fissi per ridurre le spazio

160/80m Coaxial Loop Receiving Antennas
I built one for 80m. I found that with a proper pre-amp, such the Palomar series, or Ameco's PT-3 there was a significant lowering of noise
160 meter vertical antenna's base loading
There are actually two coils, connected in series. The upper part of the winding consists of 37-3/4 turns
160 meter Half Sloper with radials
This is an antenna system made up of four 65 foot verticals with a quarter wave spacing. With radials this system takes up a 200x200 foot area
Invisible DX Antenna for the Low Bands
This paper describes a multi-band DX antenna for the 160m-40m amateur radio bands with low visibility but great performance for long distance communication
