How short is "short"? I have five coax from the shack to the top of the tower.
Each is 88 feet. Is that too long?

Yes, you can use coax lines as pathways for your ladder line to enter the
shack. Once in the shack you can continue the run of ladder line to your
tuner. The short lengths of coax will have minimal effects on the impedance
bumps caused. On the outside you can also install a couple spark plugs as
lightning surge arrestors and put some 1+ megohm resistors across them as
static bleeders. Works nice.

Subject: [TowerTalk] Ladder line entrance
As I will move my shack from being rather "primitive" to be more lightning
proof I need to figure out how to enter my ladder line from my Windom
antenna.
My access panel has multiple coax entries and I wonder now if I can use two
(2) coax cables to enter the ladder line.
Previously the ladder line "just" went through the wall with two wall
feed-throughs and I always disconnected the wires from my tuner and
connected them to a radiator in my old shack.
I am not willing to drill holes in my new shack (if I can avoid it) but
instead utilize two (75 ohms) coax cables, one for each pole on the ladder
line and put my tuner at the other end. An other solution woud be to move
the tuner outside the shack but that require a remote.
Anyone with experience?
