Tony,
How far is it from your rig to the entrance point? How high in
frequency do you wish to go?
On HF you can run a short distance with coax and then use a 1:1 or 4:1
balum at the outside side of the entrance point. The loss will be very
little depending on the distance and HF freq.
I have used the parallel coax but with shields tied together at both
ends as a pass through a thick basement wall. I didn't use that method
for a long distance
since I was concerned that it might be more unbalanced than balanced.
Hope other will chime in.

All:
My shacks location makes it difficult to keep ladder line away from
other cables that enter the house. Someone suggested I use 2 runs of
RG-11 coax in parallel to route the coax inside the house and then
connect the two to the ladder line outside.
The coax shields would connect to the tuner ground and the center
conductors to the tuner output terminals. The shields are left open at
the end where the coax center conductors connect to the ladder line.
Has anyone tried this with a doublet?
Tony
