Delta Loop Ideas Please
NomadW8 wrote:
A full wave 20 meter delta loop, fed with open wire, ladder line or even TV twin lead & a tuner will load up on all bands 10-40 meters. Performance on 10-20 will be good, 30 & 40 a little less so. EZNEC says the feedpoint of a 20m loop will be about 3000-j13000 on 40m. The SWR on the ladder-line line will be around 130:1. For better performance on 40m, install an insulator opposite the feedpoint thus turning it into a dipole of sorts on 40m. Short across the insulator for 20m operation. -- 73, Cecil http://www.w5dxp.com |
