80m Band Short Dipole
Total Length 24 m 79 ft constructed with enamelled wire 0.5 mm diameter

Antenna for 80 meters in garden 46ft
A 46 ft multi band antenna for small gardens that works well on 80 meters

A Wideband 80mt dipole
This antenna covers the whole range at less than 1.5 : 1 SWR, depending on the height above ground

Coil loading of an 80m Dipole for restricted space
Lenght of around 20m (66) with operating frequency at 3.6MHz

Dipolo gordo para 80m
The construction of this antenna is not very difficult you have to be careful to thread the 11 CDs

50 MHz preamp Gain 26dB with the BFG135

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

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
