Jeremy,

You could try and off-center fed dipole, a G5RV or even a dipole with the feed point on tree 3 and the two
elements strung between trees 1 and 3 and trees 3 and 4. Get it as high as you can. Radiation pattern will be
skewed but at least you'll have some operation in most directions.

Another try is to run a dipole from tree 1 to four (looks like about 100 feet if my math is right), and feed
from the end at tree 4. Use a tuner! Or even center feed it and run your coax along the ground back to the
shack.

Neither of these solutions produce a textbook solution, but both are workable to a point. Sometimes you just
have to bite the bullet and accept your limitations as best you can. I don't have the room available you do
and I'm settling for 40-10 meter operation thru a "Carolina Windom" ( variation of the OCF dipole) I just
ordered from Radio Works. When I get it up we'll see if it works. I understand as well that I'll never have
anything up that will function on 160.

Of course, theres always the roof mounted vertical. I've been using a ground mounted Butternut for about a
year with reasonable results.

Good luck in your quest.
