Balancing is often used to optimally match balanced antennas to unbalanced coaxial cables. These can be made of coaxial cables or toroidal transformers
Balun HF 1,5KW
Vengono illustrati negli schizzi sottostanti, i dettagli costruttivi per la realizzazione di un balun H.F. trifilare in aria in grado di sopportare oltre 1,5KW

23cm Yagi Antenna building Finished antenna at 1275 MHz SWR under 1:1.5 at resonant frequency
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
30 Volt Computer Power Supply Stack A bonus was that i discovered that these did not need a standby load connected to the supply to keep them running just apply mains power and close the Start lead to ground
