I've been using an 80 m horizontal loop for as long as I have had my license, about 15 years. It's a bit irregular with two supports on my house and three in trees, height is 7-12 meters. I feed it with open wire feeder to an indoor Elecraft 4:1 balun and then use the tuner of the K2 or K3 to match it to the transceiver. I've done 8-bands CW/digital DXCC, 80 - 10 m, with the loop as the work horse.
My decision at the time I put it up was very much based on the simulations that L. B. Cebik, W4RNL published. His articles are kind of hard to find on the internet now, but his best ones that I have on my hard disk are: Horizontally Oriented, Horizontally Polarized Large Wire Loop Antennas My Top Five Backyard Multi-Band Wire HF Antennas Notes on All-Band Use of Horizontal-Plane Loops Horizontal Wire Loops How Big? How High? What Shape? These articles answer most questions on directional performance as well as impedance and SWR. 73 ----- Sverre, LA3ZA K2 #2198, K3 #3391, LA3ZA Blog: http://la3za.blogspot.com, LA3ZA Unofficial Guide to K2 modifications: http://la3za.blogspot.com/p/la3za-unofficial-guide-to-elecraft-k2.html -- View this message in context: http://elecraft.365791.n2.nabble.com/80-Meter-loop-question-tp7615830p7615857.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
