Topband: FW: Hi-Z Around Trees

[Jeff AC0C]

Sorry to hear that.  But to avoid confusion for the guy asking about the 
trees case, we should be crystal clear that houses (which are filled with 
metal stuff) and antennas (made of usually resonant + metal stuff) are in a 
*completely different category* than a minimally interacting thing like a 
tree, especially when it's several feet from the antenna.

I could never get my hiz 2-3 (3 element,4 directions) working on my small 
quarter acre lot.  Too close to trees, houses and antennas.  Worked with
Lee for a long time trying.  No luck.  N3HEE

Lee,

Thanks for the guidance.

I plan to use 20-foot fiberglass tube with a wire down the center for
Hi-Z array elements. Would you expect sensitivity to nearby trees to be
about the same for these wire elements versus aluminum tube elements.
