Antenna 10m 28 Mhz Links →
Antenna 28 - 144
The dual band antenna is a 28 MHz double square, on the carrier beam of which a 144 MHz nine element wave channel is fixed
Build a 10 Meter Technician Class Dipole
It is a half wave dipole designed for the center frequency of 28.400mhz but should cover most of this 200khz spread with low SWR
Dismantable Yagi for the bands 10-17m
The middle parts consist of 2 m long 20x1,5 mm aluminium
Antenna delta loop 10 metri
Antenna multibanda realizzata con due canne da pesca in fenolico lunghe 7 metri
10 meter antenna 5element
Boom tube Ø 50 x 3 mm, elements tube Ø 20 x 2 mm, on middle section tube Ø 16 x 2 mm on both sides

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
