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

Take off angle of horizontal antenna For horizontal polarization, the electric field will move sideways on a horizontal plane, while for vertical polarization it will oscillate up and down on a vertical plane
Build a Three-Way Antenna Switch and Displa To use a wireless relay to select one of two high current capacity power relays
Calculo da Antena Bazooka A double bazooka antenna is a combination that has a complete coaxial wave multiplied by its velocity factor and a total end-to-end length of 1/4 wave for each side affected by another driver shortening factor
