[TowerTalk] RFU-503 Was: quick waterproofing for PL-259 connectors?

[Kevin Normoyle]

interesting Martin. Good feedback.

Surprisingly, I've found *no* references to hams using these. (on the web)
I noticed the rf in industries engineering drawing at

http://rfsearch.rfindustries.com/drawings/rfu-503.pdf
is from 1992, and updated in 1999.

Noticed they specify an aditional step of using heat shrink (1.5") over
the cable and connector, without covering the shell. Do you do that?

Seems like this connector would be pretty foolproof for a short-term 
waterproof
connection.

I'm waiting for the inevitable "I used/replaced hundreds of those in the 
past and
they weren't worth the html page they're printed on"....:)
