Antenna 6 meter Links →
144/440mhz Biquad
This is a vertically polarized Broadside and Collinear Array each Loop is a vertically polarized Broadside Array both the right and the left side of the Loop is a bent 1/2 wave
50 MHz 6 metre Delta Loop
A 25/30-foot fishing pole of the type used by a lot of Summits on the Air operators as a mast. For portable use
50MHz halo antenna for mobile
It may be better to make the loop 600mm diameter instead of 500mm to account for the lower frequency
50-MHz Quadlong
The dimensions of the 50-MHz-Quadlong,Diameter for the loop and the reflector 12 mm or 12/6 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
