Hi Ed One of most impressive study about Tree and antenna performance was presented few month ago by Dr. Kay Siwiak, KE4PT during the South Florida DX association. The study was based on years or resources at Motorola about RF on living body.
Live tree does affect RF performance. There are more information on QST Feb 2018 pg 35 to 39 , Kai Siwiak, E4PT,and Richard Quick, W4RQ Here you can download the presentation https://qsl.net/k4fk/presentations/2018-May-02-KE4PT-LiveTrees-SFDXA.pdf Very interesting stuff. I love the last comments on page 18 "In Practice, everything works, but we don't know why" " In Theory, we know everything, but nothing works" We combine Theory and Practice: NOTHING WORKS, AND WE DON'T KNOW WHY! 73's JC -----Original Message----- From: Topband [mailto:[email protected]] On Behalf Of Edward via Topband Sent: Sunday, September 23, 2018 1:40 AM To: [email protected] Subject: Topband: Inv L in Tree Has anybody snaked a wire up a tall tree trunk to make an Inv L?
