As far as simple, workable antennas for QRP work with the peak of
the roof and a tree 110 feet away....well....I would put out 110
feet or so of wire from the peak of the roof to the tree. I would
use either a short piece of coax (some balun or isolator at top
to keep RF out of house, but, then again, at 5 watts you probably don't
need to keep RF off the feedline !) OR if you can get reasonable clearance
for it - use twin lead or open wire line to the tuner. Just feed
it from wherever you can. The end is fine, somewhere in between
is fine also. If the coax is short you sacrifice nearly nothing in
losses due to high SWR on the line. If the feed is more than 50 feet
or so, you might really try to use the open wire or TV twin lead.
Really easy and probably as good as any other solution.
