I had some stuff which looks like gooey puddy that is a coaxial seal specifically intended for weatherproofing various connections. It is something you just smear over the connection and it forms a water-proof seal. Another option is to buy some silicon dielectric lube which is used to seal sparkplug wires, which you can get at an auto-parts supplier. Finally, I undetrstand Radio Shack has some Teflon tape which is intended for sealing connections. Haven't worked with that stuff, though. Steve [log in to unmask]
