The design
The folding Hexbeam is a 2-element directive antenna for five amateur bands (20/17/15/12/10m band, 6m band optional). It consists of wire elements attached to a support structure in a concentric way. The center post carries the support cords and is a coaxial feeder for the drivers. The driver/reflector arrangements are fixed to the fibreglass spreaders.
The feedpoint cord support is molded onto the center post. Connector SO-239 (N type socket optional at no extra cost)
The hub takes up six swivel spreaders and electrically isolates the center post from the mast or rotator underneath
The spreader sections are connected with locking swivel joints
