Greetings, all- Here is a small tidbit of possibly useful information in this period of low sunspot activity, which probably everybody but me knew anyway.
The PAR EndFedZ is a popular backpacking or portable semi-QRP (25 watts maximum) multi-band antenna covering 40, 20, and 10 meters. (It will also cover 30, 20, and 10 if the wire "stinger" is shortened.) Being a half-wave antenna, no radials are needed. I found that if both sides of the coax coming out of the PAR matchbox are tied together and treated like a random wire, the internal tuner in my Icom IC-703 would match it on 80 meters, with a resulting SWR of 1.2. I used about a 34 ft. counterpoise with this setup. I'm looking forward to seeing if the internal tuner in my KX-1 with the forthcoming 80 meter board will also match it. The IC-703 was unable to get a match on the WARC bands or on 15 meters. Sorry. I think a more robust tuner could probably match those bands as well. An experiment for another day. 73, Grif, KF4JG Sorry, the previous attempt to send this had unacceptable formatting embedded in the text. I don't know how much went through, but some of it got bounced. _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
