Lightweight and easy to install beam antenna (Design G3TXQ) for portable activities.
The HEX6B is a shortwave beam for the six bands 20, 17, 15, 12, 10 and 6m. The design follows the ideas of G3TXQ who was the first ham radio operator to present this antenna. However the mechanical construction was refined by EAntenna with their long-standing experience of antenna engineering. The result is an efficient portable antenna for the classical DX bands, which can be used due to it’s low weight also for DXpeditions and vacations.
The HEX6B works as two element beam on each band. Ready-to-use wires and ropes are fixed to the glassfibre struts, no tuning is required! Due to the mechanical tension of the struts the beam is stretched to it’s fixed size all he time, there is no sag on the wires. The radiator dipoles are connected to the vertical center support, each has it’s own screw clamps. The center support is designed as a coaxial transformer and balun. This transformer is responsible for a very good match on each band, and the fact that only one feedline is required for all bands. The gain is approximately 3 dBD or better, the front/back ratio is between 13 and 22 dB. The matching transformer achieves an SWR of 1.5:1 or better on all bands except 10m, where SWR is 2:1 or better. Each band can be used in full bandwidth without a tuner. The maximum allowed power is 5 kW. The glassfibre tubes are double coated against UV radiation.
The setup of the HEX6B 6 band beam is simple and can be done by one preson in approx. 30 minutes. For installation the 6 struts are assembled and fixed to the center pole. Ready-cut ropes from the top of the center pole to each strut are installed for the typical bent shape of the hexbeam. Then the ready-cut wires are fixed to the struts, and electrically connected to the center pole. All ropes and wires are already cut to length, no tuning is required. Due to the low weight of only 8.2 kg the hexbeam can be installed on a light aluminium push-up mast. Rotation is either done with a small 12V rotor or by hand. The HEX6B can install at poles with a Diameter from 28-52mm.
