[TowerTalk] Sealing coax connectors

[Marlon K. Schafer (509-982-2181)]

Just remember that anything that's easy to get off also makes it easier to 
let water in....

I hate taking my connectors apart.  Especially when it's well below freezing 
(like the other day).  It's a major PITA.  But I've found that a needle nose 
pliers, sharp knife and some patience does the job nicely.  I've also not 
had any connectors leak in many years.  And I've done HUNDREDS of them as a 
WISP.

Perry,
OK, great.  It is perfect then for applying first before the tape wrap and 
be able to take the connector apart later if need be.

thanks perry
