I don't think you will see much impact on HF, but the foliage losses can
become a factor as you up into VHF, UHF, and beyond. Also, at HF, you're
rarely trying to pull signals out of the noise floor.
At my QTH my tower (around 70') was once out in the open, but all the trees
have grown up around it and it is largely sheltered by trees within about
30-50'. On HF I don't notice much transmit/receive difference at all, but
the tower and antennas are well hidden! In addition, the surrounding trees
provide a wind break so the structure is not getting the high winds
full-blast.
Solar-caused band conditions will have a lot more impact on your
installation than the trees.

Subject: [TowerTalk] Basic Question about Antenna Height and Treetops
I am moving to a home situated on a hilltop. Nearest same height hilltop or
higher is about 1 miles away. The home is surrounded by dense (typical New
England Forest) 80' high hardwood and fir trees and my planned small tower
(budget and local codes) gets me only to a 50-60' antenna height. The trees
will be within 50- 75' from my nearest Yagi ends. How badly can I expect
my signal to be affected by the higher surrounding tree tops? I cannot
build a tower to match their height.
thanks and 73
