I bought 1/4" dowels from Home Depot and cut them in 3" lengths. I was using 26g wire so I drilled 1/16" holes as close to the ends as possible and then I strung the wires through the holes tying each end off to make the whole thing somewhat flat and about waist high. I spaced the dowels out every 12" or so. I then went through and dipped each end of the dowels in Plastic Dip 2-3 times each. It takes a little practice, but it is not as messy as it sounds. It secures the wire to the dowel very well. I used a small piece of Lexan I had laying around to make the apex of the antenna and secured the legs and feedline to the Lexan piece. I put the apex and legs up with 20lb test fishing line and that thing stayed up in the same spot for over 5 months. We had a cold snap and pretty good wind storm here a couple of weeks ago and a branch from one of the trees finally brought it down. I plan to repair it and take it to Alabama next week for Thanksgiving and a little op time at the in-laws. I had some BNC to RCA socket adapters around here so I took an RCA plug and soldered a 3" piece of RG174 to it and put banana sockets on the other end. I put banana plugs on my feeder. I made the stubs with banana sockets on one end and plugs on the other also. > I'm also playing around with the idea of bringing an > open > wire feeder into my shack as well.

Most are based on a design by Charles Lofgren, W6JJZ. If you do a search on Z-Match or W6JJZ, you'll find all kinds of info. I bought most of the parts I need and found some surplus plastic tuning capacitors that will work nicely. I was hoping to try it out this summer - but you all know how that time thing gets away from us :-) 73, Dave W8FGU _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
