Hi, The problem is that because of the type and position of the connectors on so many of the Trimble, Novatel, etc., antennas, it's practically impossible to seal them with something easily removed like self amalgamating tape. Antennas like the 58532A make life a lot simpler by hiding the connector up a tube.
The idea seems to be that nickel plated brass TNC connectors are all that's needed, but it's not that simple - particularly for coastal or marine use. In fairness, even a lot of manufacturers of dedicated marine gear vastly underestimate where water can get to and what damage it will do - at least they did back in the 1990's when I was working with that stuff. It could take a very long time (if ever) for them to be convinced that what works in their nice little environmental test chamber could possibly fail out in the big bad world! >However, for the past 10 years or so I have been using double wall >adhesive lined heat shrink tubing.

I was not convinced about adhesive lined heat shrink when I tried it since it usually didn't seem to bond well enough to withstand bending, although I've not tried the newer types. It probably wasn't the premium quality tubing Adrian mentioned either. The PIB based self amalgamating tapes had to be well taped up and did not like oil, but the EPDM and PE ones we used were less sensitive although they still needed to be taped up. Since I wanted to be able to swap them easily, I eventually got some Amphenol ARC TNC connectors for the GPS antennas, but still chickened out of using the heat shrink supplied and went for self amalgamating tape instead for sealing the crimp. I really should try the unused heat shrink on something to see how it does.
