A idea for 160 Metres Antenna
It consists of 140 feet of insulated wire, the first half of which 70 feet is space wound on an insulated tube

10-160 meter horizontal loop antenna
This 10 - 160 meter tuned horizontal loop antenna is powered by a 450 ohm ladder line completely in the ham hamlet on a Palstar AT1500BAL balanced line antenna tuner
160 Meter Tunable Counterpoise
I have been asked many times to explain how to adapt a Tunable Buried Counterpoise System to a Horizontal Loop NVIS
Antenna end fed 160 metri
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

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
Interface-for-digital-broadcasts-with-integrated-audio 4-port HUB, with a TUSB2046. With port 1 of the HUB we drive the FT232RL; with port 2 the PCM2904, furthermore, we decided to leave ports 3 and 4 free
