When I lived in the Seattle area I had a number of 110+ foot tall
Douglas firs about 20 feet from my antenna, completely covering
the path to Europe. I wondered the same thing - are they
absorbing RF?
As far as I could tell, the answer is no. Signal strengths from
other directions at about the same distance were the same. My
observations went on over a seven year period, during which time
I put about 25,000 QSOs in the log, mostly RTTY, mostly during
contests.
I realize this is not a scientific comparison at all, but after
that much operating, I am sure my observations were correct.
Hope this helps.
