Well, I thought I had saved it, but looking through my folders, 
I find I did not save a particularly interesting and informative 
note on how to properly seal the coaxial cable connector joint 
at an antenna.  Specifically, we (a couple of member of the 
Johnson Space Center ARC) will be replacing the 2m repeater 
antenna on the penthouse roof of the JSC administration bldg. 
Probably on Thursday.  

The antenna is a G7-144 with an N-type connector.  
Do I need to seal it? 
I say no.  The existing feed is not sealed in anyway and has 
been that way for at least 10 years.  My first thought, if it did 
need sealing, was to use good electrical tape (it was mentioned 
and specifically referenced as 3m 4488 ??? in the missing note) 
over some other type of sealer (similar to, but not the same as, 
coax-seal, I think it said).  

One of the other going up with me is mentioning some sort of 
liquid tape. I have not seen it referenced at all on the tower reflector
(probably for good reason).  Anyone use it? Any negative comments 
on it?  

Thanks for any info....
