It would not look good for a preacher to be hit by a cruise missile. :-) Hmmm,
maybe the flaming arrows of spam are from the cia???

Ok, I will scrap the 4 pipes around the house for loop's extra elevation, and
use them for elevation for a 2m J-pole.

With the power company feedline coming in at the front (away from feed point.
would a "U" shape (that is a loop with a gap around the power line) work. I
think that I just realized the answer. It would or could cause an unbalanced
situation which could lead to all sorts of problems like RFI, unable to tune,
etc....

I am also thinking of running the loop along the backside of the house and
then instead of continuing to run along the side of the house, run the wire to
an old unused billboard (about 20 or 30 feet high) and then from the billboard
back along the front of the house, and then instead of along the side, run it
to a tree (the only one on my property) and then back along the side of the
house. The feedpoint would be on the backside about 1/4 or 1/3 from the tree
side.

An idea, if, I use the 2 of the pipes as additional supports placed at the top
of the side eaves , I could run a wire from the tree over the roof to the
billboard, sort of an inverted V or a droopy end dipole with a slight bend on
one side. And if the pipes are placed just right, then I would not be running
a wire under a power feed line, like the loop on the eaves. It would be random
length, and feed about 1/3 or so from the tree end, unless I got more
ladderline. Total length about 60 or 80 feet at about 20 or 30 foot sloping
down to about 10 or 15 feet at the tree. Let's see, a random length dipole in
the clear (by a few feet), should out perform a loop under the eaves? Easier
matching, antenna in the clear, less RFI, better for NVIS and DX. Maybe a
better antenna?

Can an OCF dipole be feed with ladderline?
What is the best way to run ladder line over asphalt shingles?
