[TowerTalk] Trees and Verticals

[Roy K. Breon]

 I remember reading an article in an Army publication from the
signals group in Ft. Monmouth NJ which described a battlefield
expedient antenna which used a tree as the antenna.  They coupled
to the tree by means of a multi-turn loop around the trunk of the
tree.  I don't remember the results of the antenna's performance.
Perhaps some other group members remember the article?

Subject: [TowerTalk] tree conductivity

I'm looking around for data on electromagnetic properties of
trees 
(mostly electrical.. I don't think trees have any appreciable
magnetic 
properties)..

I found this interesting reference where they measure tree
conductivity 
to find soil contaminants

but no numbers
