In designing the antennas presented on our web pages, we found that several pieces of hardware were needed frequently for each of the designs. These can be used either horizontally for planar beams or vertically as quad loops or cubic quads. We suggest this mostly for backpackers who need the lightest designs possible.
All units come with stainless steel set screws.
Two internal set screws lock the hub to the mast or boom. Each spreader is also locked in place with two set screws. The depth of the socket holes is carefully controlled so that the distance of the spreader tip from the central axis is increased by one inch. These can take 40 lbs of tension without breaking under static loading. Normally the monofilament line breaks first, and 40 lbs is well beyond any loading that can be imagined for these light weight structures.
