[TowerTalk] Running coax into the basement

[WA2BPE]

I use PVC pipe (size as required - use 1/2 to 4" here) - run a piece 12-18" thru the header and clamp it to a joist (or whatever) using a conduit clamp.  On the outside, I use a 45° street
el.  This is cemented to the straight piece before running it thru the wall and is caulked with silicone RTV.  If you need (or want) more of a bend, a section of a sweep works well too.  If
you have Vinyl siding, it is best to install one of the plates used for mounting electrical outlets, etc. to allow the vinyl to move (as it needs to).  After running the cables (be sure to
have a drip loop), just stuff the remaining space with foam plastic or fiberglass insulation - recess it it, say, 1/2" to keep it dry.  I have used this method for 25+ years with zero
problems - water, bugs, etc..  Your idea of using a pipe cap is "OK", but it is nearly impossible to really seal the coax to it without damage and water has a way of going where it wants.
