Hello all, I've been hiking with Guy, N7UN, and as some of you know he's a "rocket" on the trail. He usually brings along a tri-band diople to use on the trail. His dipole is a 40m dipole and he just connects less wire for 30m and 20m. I thought I'd build one and try it out.
I started with a 20m diople and tuned it. The wire is # 24 gauge stranded whit with 19 strands. For the center I used a panel mount BNC connector. After tuning 20m, I tied a fishing swivel to the 20m end and also installed a female snap connector. I then did the same for the 30m connecting wire, but used a male snap connector on both wire ends. I then connected the wires and tuned 30m. Next I did the same for 40m. I now have a dipole that works great with my KX1 on 20m, 30m and 40m. If I want to work 20m only, I just put up the basic diople. If I want 20m & 30m, I add a short piece to both ends. If I want 20m, 30m and 40m, I then add the last wire piece on both ends. Or, I can put the dipole up as a 40m antenna and just disconnect the jumpers to change bands. In fact I just worked VE2PID on 40m. The whole antenna without coax weighs-in at around 3 oz or less. Thanks for the idea Guy, N7UN! 72, Roo Bear Ed, WA3WSJ PB # 2 _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
