There is a trap here waiting to bite the unwary. It's called ground resistance. Unless you have a very good ground system under the parasitic element you may not get enough current flow in the element for it to work properly. This doesn't happen with driven arrays as the Rg is figured into the feed system. 73, Roger -- Remember the USS Liberty (AGTR-5) http://ussliberty.org/ _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contesting.com http://lists.contesting.com/mailman/listinfo/towertalk |
