[AMRadio] coax lead in

Fri Apr 1 22:23:15 EDT 2011

I agree. I have the RG213 feeder to my vertical in 1 1/4" PVC run about 40' from 
the house with weather heads on the ends of the conduit where it stubs up by the 
antenna and by the house under the window where my entry panel is.

Drilling holes in PVC pipe to "let out" the moisture will only allow 
moisture to enter.  A tight fit is the only way to go.  It has worked for 
me.
