I managed to work David on 160m ssb, it is sort of in my backyard. But even
then, the qso was not easy. I gave him a CW key before he left
but I doubt if he will try to use it.
There are always a team on Marion Island but since about four years ago,
they are not allowed to add any more antennas th
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) tha
I live on several acres that is a watershed area with a relatively high fresh

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 ha

OK - found out they will be on the Island(s) for a work assignment...thanks to
all that sent me the info! 72, Jim R. K9JWV

This from the ARRL DX news e-mail:
PRINCE EDWARD AND MARION ISLANDS, ZS8. Nadia, ZS8A plans to soon be QRV from
Marion Island. In addition, Carson, ZS8C and David, ZS8Z are active as time
permits. QSL via operators' instructions.
BUT - I can't find a web page (looking for band plans, etc.)
Some time ago I attempted to make direct measurements of the HF conductivity
of trees, at least for the trunk and limbs. I simply put a two rings, with
nails to penetrate through the bark, around the trunk spaced a couple of
feet apart. Basically what I had was a resistor. I then measured the
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:
