[TowerTalk] using coax as ladder line

[Donald Chester]

But if you are talking about just a few inches to get through the wall of 
the house, the loss shouldn't be any higher than with feed-through 
insulators.  I would use some larger size coax than RG-213, though.  With 
open wire tuned feeders, the rf voltage can be very high - enough to exceed 
the rating of the coax.  I'd go for some of the 1-inch plus diameter stuff 
used in commercial applications.

Or what about just a plain old pair of ceramic feed-through insulators?
