Hi Brian and others.
Brian should have added with his comment, that he has made numerous
qso's to VK (that is with me and other VK's) with his "poor antenna" on
top band overs the past years and when and if he can move the wire away
from the tree trunk, then he will no doubt make many more qso's.
What a difference one S point can make or even a half an S point, when
you move the wire away from the tree, by 2 or 3 feet, if possible.
When I consider the number of dx qso's I "almost made" over the past 30
years or so, on Top Band and what I could have worked, if only for one S
point, on TX and or RX.
If only I had the drive or time to make such a small improvement to my
antenna system.
Cheers from Ron, vk3io.

Ed, Gary and All,
Seeing as I have had my Inverted L ( 85' / 27M vertical ) against my tree's
trunk ( actually touching it - oops ) since I installed it, and as I also have
tress in the elbow, I may have to try and move it out some after reading all
the suggested articles. The only reason it is like it is, is for convenience,
as I have no towers ( or trees in the right location ) to hang it off of atm so
it was either that or no Inverted L.
All I can and will say is that just "anecdotally" speaking and nothing else, it
will still work, not as good as one that is stood off a few feet I am sure but better
than nothing if it gets you on the air. Or to put it another way, a poor antenna is much
better than no antenna at all.
Good Luck and remember YMMV

Subject: Re: Topband: Inv L in Tree
Ed,
FWIW, I'm using what used to be an INV-L.
I laid out a radial bed as well as
possible, next to a marsh. I am in a
hurricane area and with the winds, the
trees have fallen over. I originally shot
a line over a tall branch with a spud gun
I made (see it on my QRZ page, at the
bottom), at that time it was an "L".
The branch came down and I used another
branch, albeit farther away. With
attrition, I am now using a tree maybe 30'
away from straight up. Doing it the way I
did allows me to have a radial bed away
from the trunk of a tree. I can't move the
bed so the type of antenna had to change.
I am using WD-1A field telephone wire for
my antennas, with its SS solid core it is
incredibly strong and it is so thin it is
very hard to see.
It's not nearly as good of an antenna as
many here use but it is quite good, even
as a sloper. I was able to work 9X0T on
160 tonight and could barely hear him with
the QRN & RFI but he heard me. Point being
that a sloper works very well on 160, you
don't "have to have" an INV-L.
Whatever you go with, I wouldn't run the
antenna next to the trunk. I would keep it
some distance to the trunk and as long as
you have enough length for radials &
antenna & I'd use some method of getting a
stealthy wire like WD-1A up over & into
the tree-top and down to the radial plate.

Has anybody snaked a wire up a tall tree trunk to make an Inv L?
Any interaction? Success?? Has to be stealthy because the tree os
my neighbor's :-)
Thanks,
Ed NI6S
