1. [TenTec] antenna analyzer reading? (score: 1): Author: "Denton" <denton@oregontrail.net>; Date: Sat, 20 Feb 2010 08:46:26 -0800; Hi all...a little off the Ten Tec groups, but... I have an MFJ 259B that I use and am a little confused about the R and X readings... I am trying to determine the true losses of my 235 ft horizontal; /archives//html/TenTec/2010-02/msg00252.html (10,527 bytes)

Johnson" <geraldj@weather.net>; Date: Sat, 20 Feb 2010 13:49:47 -0600; Most of the R of a decent antenna is radiation resistance, not wire loss resistance. You can't tell about an antenna's efficiency or looses by looking at the feed impedance. Unless its a very well do; /archives//html/TenTec/2010-02/msg00257.html (12,386 bytes)

G5RV's articles are available in the ARRL's antenna books. He says that the antenna is a 20 meter antenna that was built exactly. That is, it exactly fit; /archives//html/TenTec/2010-02/msg00269.html (17,425 bytes)

Its a compromise and the feed line lengths are critical. Yours seem a bit short. Now its no longer resembling the G5RV.

The G5RV started life as an antenna specifically designed for 20 meters. Period.
