What's the edge to edge dimension on 450ohm line?

Hi Jim, The ladder line I have is .931 inches edge to edge. As such
I would not recommend trying to stuff it thru 8' of 1/2" PVC. I would
at least use 1", and even then you will have some compression of the
ladder line. Changing the spacing of ladder line will change its
characteristic impedance.
Thinking about it, if you force ladder line into 1/2" PVC you will
have to distort it into a "U" shape, and have a bad time trying to fish
it thru the PVC.
