[TowerTalk] Weather/water proofing aluminum tube ends

[Bill Winkis]

Yes...use one of the new HD - adhesive Shrink-Tubing...cut the shrink 
tubing long, when you heat and shrink, clip the overhang and let it 
cool.... I use this to seal coax connectors etc....have two test 
pieces one  on the end of a piece of aluminum antenna tubing; the 
other  a PL259/barrel coax joint...they have been under water for 
since Thanksgiving 07, I opened them last week and they never leaked....
This new HD stuff is great...
