Sentinel Hex Beam 20m Single Band

RadioWavz 

Sentinel HEX BEAM Antenna

Based on the original design by G3TXQ


 

The Sentinel Hex Beam is a  directional antenna that provides great performance and reduced size.  

The G3TXQ broad band hexagonal beam for 20 meters is constructed of six fiberglass arms and insulated stranded copper wire.

The Senenel series single band hex beam consists of two elements. The driven element is in the shape of an “W” and the reflector element is wrapped around the four spreaders to the back. The elements, insted of using tubes we use wire.  This reduces the need for a heavy supporting structure. The supporting structure consists of six flexible fiberglass arms attached to a base. The arms form a hexagonal shape hence the name "hexagonal beam".
