I'm getting the ladder line bug and am wondering how to feed it - the 
shack is between the outside wall of the house and the 2 car garage.  So 
I run about 55 feet of coax today from the shack, through the wall along 
the ceiling of the garage before going out the wall of the house to the 
mast and then about 40 feet into the air.

That said, the route the coax takes is along no metal or near any metal 
- only the metal pole outside is where I will have to come up with some 
creative method to keep the ladder line away from the pole.  I have read 
that anywhere from 4 inches to 18 inches is recommended to keep the 
ladder line away from the mast.

That's another idea i'm thinking about - just using the coax I have now 
and running the ladder line to the 4:1 balun and then coax through the 
rest of the house.  But I have no idea how well this will work.



All of this needs to run in the presence of full legal limit power so 
i'm not sure what other considerations there are...



Thanks,
