Terry, If you need a beam with a smaller footprint, have you consider one of the many hex-beams that are available? I've had one for several years and really enjoy it. I have a 5-band model that covers all bands, 20m- 10m, WARC bands included. Mine has about as much gain on each band as a 2-element beam, with a moderate front-to-back ratio (about 9 db or so). Mine is an older model of the original Traffie Technologies HX5-Bi. Traffie is no longer in business, but there are a few vendors in the US that offer beams or kits for beams, and if you visit http://www.karinya .net/g3txq/hexbeam/, there is a wonderful tutorial on the hex-beam, along with links to plans so you can homebrew yours. I have mine on a 30' Force 12 tilt-up mast, so it sits just a few feet above my roof line. It has something like a 21' turn radius, and about a 9 pound windload. And the whole antenna only weighs in at about 25 pounds. With this antenna, and my K-Line, if I can hear 'em, I can work 'em! Good luck with your move and setting up at your new QTH. 73 de, --Ian Ian Kahn, KM4IK Roswell, GA EM74ua [email protected] 10-10 #74624 North Georgia Chapter #2038PODXS 070 #1962 K3 #281, P3 #688 KAT500 #860, KPA500 #1468 On Fri, 2017-05-19 at 23:40 +0000, Terry Brown wrote: > I apologize that this is not a direct Elecraft equipment question, > but > having the K2, KX2, KX3, PX3 and KXPA100, I thought I would ask.
