See http://www.kkn.net/dayton2011/N4ISWallerFlag.pdf I saw that statement as well, which noted a gain of -53 dBi. My NEC model, using Carlos's dimensions over lousy soil, computes -44 dBi with a peak at 24 degrees. 73, Jim K9YC _________________ Topband Reflector Archives - http://www.contesting.com/_topband |
