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.

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.

  Greetings Top-Banders, I have been away for a couple days, sorry for
  the late comments.
    The fact is, for me there is no definitive answer to the effect of
    trees on the Hi-Z arrays. I have made tests measuring phase shifts
    and amplitude changes with a variety of objects around these
    elements. My original thoughts after the tests were that any tree or
