But the antenna works fine on the handie talkie. You might want to try repeating the measurement with the MFJ 259 held up beside your head as if it were an HT. I've been told that HT duck antennas are often tweaked for best match and lowest SWR when used in this position, with a significant amount of capacitive coupling to the user's head. Measurements of a couple of 'em with my 269 seemed to support this - they "read" a lot better in a "typical HT use" position than they do if the analyzer is being held out at arm's length. -- Dave Platt AE6EO Hosting the Jade Warrior home page: http://www.radagast.org/jade-warrior I do _not_ wish to receive unsolicited commercial email, and I will boycott any company which has the gall to send me such ads! |
