[TowerTalk] Basement entry

[Kenneth Cechura]

another option would be (since you're planning on running the PVC through 
the wall, i would guess) to use 2" conduit and a standard feedhead with 
associated drip loops, etc.  We have one of these on the roof of the W0EEE 
station for our tower feed....   works very well!
