A Control Box for the K9AY Loop Antenna
The control box allows to switch the direction and to change the termination resistor, so I decided to scan and reconstruct the drawing and PCB design for others who may need it
Antenna Biconica
The so-called biconical antennas are a typical example of antennas for broadband measurements
Trasformatori e Chokes per ricezione in 160 metri
Di fondamentale importanza e' l'impiego di toroidi di materiale corretto, adatto alle gamme di frequenza interessate
Power supply loop wellbrook ala1530ln
Sostituzione alimentatore per antenna-wellbrook-ala-1530ln su schema LM317 con trasformatore
Rx antennas 4Square Rx Vertical Array
My frequency design of 1.825 MHz a 90 degrees line would be 33,70 metersinstead of the previously calculated 33,27 m
