What are you experiences and opinion's (if any - good/bad) on this antenna? How well does it perform for QRP? Is it a good Hide-away antenna for apartment dwellers? Any and all responses are welcome. To save bandwidth, send your response directly to me (unless there are others who missed the feed, as I did). 73 de Lynn KB0LRB ------------------------------ Date: Tue, 5 Apr 1994 19:34:10 GMT From: fluke!chuckb@beaver.cs.washington.edu Subject: Antenna stacking problems To: ham-ant@ucsd.edu In article <2nlhvm$4rt@search01.news.aol.com> ka4rru@aol.com (Ka4rru) writes: >In article <1994Jan31.191526.18186@nosc.mil>, price@nosc.mil (James N.

I THINK THAT THE ANTS WERE ABOUT 4 FEET APART ... 73 DE MIKE 4 feet was too close because of the interaction between the 40m and 15m antennas. For the high bands usually 6-8 feet is enough separation. For 15 and 40 you need 15 feet. I've tried 16 feet and that was successful. This is assuming that you keep the antennas in the same orientation. -- Chuck Bowden / WB7R / chuckb@tc.fluke.com / (206) 356-6228 Fluke Corporation / MS 232E / PO Box 9090 / Everett WA 98206-9090 ------------------------------ Date: Tue, 5 Apr 94 22:06:50 GMT From: ihnp4.ucsd.edu!swrinde!gatech!newsxfer.itd.umich.edu!nntp.cs.ubc.ca!alberta!adec23!mark@network.ucsd.edu Subject: SGC tuner To: ham-ant@ucsd.edu greg@netcom.com (Greg Bullough) writes: >I keep hearing wonderful things about SGC's automatic antenna tuner. Deserved. >Does anyone have anything *bad* to say about this beastie? If you have a close to resonant (but still bad match) antenna, the tuner can search till the cows come home, rattling away mindlessly at it's relays. A manual antenna tuner with cross-needle display takes about a minute to tune up on a fresh antenna and comparitively can match *anything*, which the SGC tuner can *not* (but damn close in any case). Only purchase this if you want hands off tuning desparately, I believe this tuner is the best on the market, if you prefer to run long wires in the middle of nowhere, bring along a manual tuner *just in case*. If your aligator clip slips off the antenna feedline while running with the tuner in the shack, be prepared to watch in horror as your tuner matches up the short little alligator clip wire on 160M, then promply starts a lightening burst and fire ball from the arcing ... ;-/ The tuner does *not* retune if it has better than a 4:1 match after switching bands, you will need to reset the power to the tuner before it will tune up on the new band.
