High-Power Antenna Tuner
The dual split-stator (250 pF/section) Millen 16250 capacitor on the left, and the 200 pF Millen 16520A capacitor on the right
Homebrew Z match ATU
My main antenna is an 88ft doublet, so I need to use a tuner with my rigs.The K3 and K2
Homebrew T-Match Antenna Tuning Unit
I decided that a T-network would be the best option and I would also include a built in VSWR meter
I meriti del transmatch
Grazie al transmatch, il generatore vede l'impedenza ottimale che gli consente d'erogare la massima potenza possibile

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
