End Fed Wire Antenna for 10,15,20 and 40 meter band
A FT140-43 toroid to make myself a homebrew End Fed wire antenna,without the need for a tuner
End Feed Half Wave Antenna
E' un semplice L Tuner che adatta l'impedenza dai 50 ohm del RTX ai canonici 2450 dell' Antenna
End fed 6 - 40 Meter Multiband HF Antenna
End fed HF antenna The end fed feature adds portable convenience, but does present another issue.The problem with an end fed half wave antenna is that the antenna presents high impedance
Endfed multibands with tunner
End-feed antenna with 1.5mm wire 36m long and T200-2 toroid - 23 double turns of one mm

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
