Antenna verticale per i 160 metri
Un quarto d'onda sui 1.850 kHz vuol dire un'antennalunga 40 metri circa, lunghezza dell'antenna si e' ridotta in totale a 8 metri e 80 cm, ovvero circa 22% del quarto d'onda lineare. la bobina di compensazione e' stata fissata a circa 32% di altezza dalla base

A Practical Antenna for 160 Metres
It consists of 140 feet of insulated wire, the first half of which 70 feet is space wound on an insulated tube. I used glass fibre tubing which was to hand, but PVC
A Stealthy HF Coat Hanger Antenna
In fact, there's nothing new on this page. It's just about a very common HF antenna that I recently built
Antenna per trasmissione Inverted L
Questa e' stata la mia prima antenna per i 160 metri, in uso dal 1986 al 1990, quando ero ancora attivo su tutte le bande

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
