[TowerTalk] Ladder line entrance

[K0DAN]

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?
