HEX6B 6 G3TXQ Hexbeam Design Bands
Lightweight and easy to install the antenna beam (designed by G3TXQ) for laptops.
The HEX6B is a shortwave beam for 15, 17, 20, six groups 12, 10 and 6 m. The design follows the ideas of G3TXQ who was the first amateur radio to present this antenna. However the mechanical construction was perfected by EAntenna with their long experience of engineering antenna. The result is a portable efficient antenna for the bands classic DX, which can be used because of its low weight even for DXpeditions and holidays.
The HEX6B works like two element beam on each band. strings and ropes ready for use are attached to the uprights in fiberglass, require no tuning! Due to the mechanical strain of the Struts of the beam is tensely to it # s fixed size all the time, there is no sag on the wires. The dipoles radiator are connected to the vertical center support, everyone has # s own screw terminals. The support center is designed as a coaxial balun and transformer. This transformer is responsible for a very good match on each band, and the fact that only a power line is required for all bands. The gain is about 3 dBd or rather the front/back ratio is between 13 and 22 dB. Adaptation transformer reaches a SWR of 1.5:1 or better in all bands except 10 m SWR 2:1 or higher, where is. Each band can be used bandwidth without a tuner. The maximum power allowed is 5 kW. Fiberglass tubes are coated double against UV rays.
HEX6B 6 band beam configuration is simple and can be done by a preson in about. 30 minutes. To install 6 uprights are assembled and attached to the center pole. ropes ready cut from the top of the Central column for each pillar are installed for the folded shape hexbeam. Then the ready-cut wires are fixed to the uprights, and electrically connected to the central server. All cords and wires are already cut to size, you don't need any tuning. Thanks to the low weight of only 8.2 kg the hexbeam can be installed on a lightweight aluminium push-up mast. The rotation is done with a small rotor 12V or by hand.
