Hex Beam for 6 meters
- This is a hex beamdesigned for six meters. It has three elements with a turning radius of 54 inches. This antenna can be built from low cost materials available from the local hardware store. By WB3BEL
2 Element beamdesigner
- This is a DOS program that will design a 2 element beam for a given frequency. The gain is about 6db's the front to back ratio is about 10 db's. The SWR will be about 1.8 to 1, so for transistor rigs a tuner is needed The only information required is the freq in MHZ..
