Folks, if you can run or intend to run coax through the wall or window or
whatever, then run the balanced line the same route. Better yet you do not
have to deal with the loss in the coax. The fact is under any circumstance
the open wire/balanced feed will have less loss than any equal length of
coax.
Remember, less loss means more RF to be radiated. Loss is heat.

I run mine through the wall with two pieces of RG-8 coax WITHOUT the
shield. Spacing is same as balanced line and uses two separate holes.
Guys, this may be a stupid question, but if you use two parallel pieces of
(long) coax, wouldn't you have twice the loss. On the other hand,
resistors
in parallel would mean half the loss. In any case, coax is lossy, heavy,
and expensive, so why would you use a long run of two coax cables?
Using short lengths to going through the wall is a good idea, but then why
would you need to tie the shields together at all and why ground them?
