I have not used the specified heatshrink on these connectors but just sealed
them in the usual way. The 'built in' weather proofing I would only consider
minimal. That said I have a couple of N connectors on the tower which are
completely unsealed, deliberatly to see how long they last. They look a bit
discoloured but seem to be fine so far otherwise. It's only been about 6
months though so far.
As I said I would stay away from the Taiwanese version but the Japanese one
looks to be manufactured to a tighter spec.

PL-259connectors?
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"....:)
