ULTRA LIGHTWEIGHT D-HEXPEDITION PORTABLE HEXBEAM has evolved as a result of customer requests to have a lightweight portable Hexbeam that can be packaged away into a small lightweight holdall and easy enough to carry on aircraft etc.
The design is based on the ever popular and reliable G3TXQ HEXBEAM as currently sold by Anthony.
The spreaders are in four couloir coded sections which simply slot together similar to modern tent poles. The end spreader has the cords attached to meet the top of the centre post and to each of the other 5 remaining spreaders I.e. 1 to 2, 2 to 3, 3 to 4 etc.
The centre pole and stub base are newly designed with lightweight wing nut fastening for each of the 6 bands as opposed to regular nuts. The centre post fastens to the hub using a single through bolt and wing nut.
Wire elements are pre assemble cut to length and packaged separately as with any other hex beam product. Feeding the elements is easy removing stay wires to stand in centre of antenna and working from back assemble 6, 10,12,15,17, and 20m elements.
Wire retaining loops are held to centre of stubmast and spreaders with very strong Velcro fastenings . Mine have got very wet and no affect what so ever.
Once built the antenna is very light and can be held upright in one hand like an overgrown Olympic torch.
An optional stand pipe at bottom allows a set of nylon retaining cords to take tension preventing moving too much in winds. I would recommend for what it costs adding it to a purchase..
Erecting can be fiddly if like me you were using a drive on mast with a tilting connection . I used a step ladder to rest mast on then climbed steps to attach the beam to the rotator . The beam sags quite a bit but like so many miricales of science seems to sort itself out when vertical as spreaders fall into place.
Feeding was via a ferrite choke connected to 20m element running coax down and a small loop at rotator.
SWR readings were all very acceptable indeed and if I say so myself performance was up on the regular Hexbeam.
Does it replace a Hexbeam for daily use at QTH no absolutely not as spreaders are more susceptible to move than the MW0JZE Hexbeam BUT this is a bespoke antenna for portable use and it performs flawlessly.
This antenna recently accompanied me to Mauritius Island and I was very very pleased indeed.
Consider a push up telescopic mast to assist in an easier mast installation
