I have used open wire feedlines in six houses so far. I drill two 3/4 inch
holes in any wall that is most convenient to bring the line inside and over
to the tuner. I ram two pieces of plastic pipe in the holes letting about an
inch or so protrude from the wall surfaces inside and outside.

When I move, I yank out the pipe, jamb stucco, wood filler and/or drywall
goo in the holes, dad paint on the repair and VOILA! Walls as good as new.

The whole thing is so easy. Why make it hard on yourselves?
