This subject has been discussed here plenty of times in the past, and the
consensus has always been that trees and other foliage near a 160m antenna
has a negligible effect on the transmitted signal. That's what I have
believed for some time.

In this case, K9LA was talking about two things:

I live on several acres that is a watershed area with a relatively high fresh
water
table.
Almost all of the land is densely populated with trees and some ranging up to
a 100' or more.
For transmit antennas on 160, I have an inverted L that goes up to 85' with
30 elevated radials. And, I also
I *very much* appreciate the many replies to my post. I've known about the
effect of foliage at VHF and above for a long time, but I think I've just
learned something new and useful. :-)
Since the vertical portion of my inverted-L is over 10 feet from the tall
oak tree (and its leafy branches)

Interesting study which suggests not placing a 160m vertical closer than 12' to
a tree, if feasible. There are certainly lots of vertical radiators working
well amongst towers. We won FD 4 years in a row using 5 watts to a random
vertical wire hoisted up the aluminum mast of a sailboat amongst

Without doubt foliage has measurable effects on the antenna when it is
close to a voltage
point (speaking from experience with loops), so Carl's findings make good
sense.
