I don't have a HI-Z, but I do have many antennas in the trees here. (and
have in the past at other locations too)
Recently, I have installed all wire & rope 4-squares on 40 & 80 and a 2-el
on 160m, all in and in some cases attached to or gently touching,
(gasp!)(wait for it.....) dunh dunh dunh..TREES !)
Worse yet, the 80m/160m arrays are partially nested and the 40m one is
partially nested in the corner of the 80m one.(maybe that's a separate
thread)
I posted my results here in 2 separate posts some weeks back, so I won't
repeat the data, except to say the only non-scientific anomaly's I see are
when the 80m array is aimed to the NW through some metal clutter and 2 sheds
(full of wiring and metal).
I used trees and did some nesting of arrays nothing bad happened like the
naysayers warned.
Would I get 1dB more gain and 2dB more F/B if they were aluminum verticals
out in the middle of a 40acre field? Probably.
I used what I had.
I'd worry more about a nearby house, a utility pole full of wires, your
neighbours 18-wheeler, anything large and metallic than I would the harmless
but helpful tree.
