Nick,
I had one of the early models of Boltek years ago.
I found the same thing, that the antenna for some reason (active components?) gets quite warm when in operation, leading me to wonder just how much current goes up and down the CAT 5 cable.
Anyway, one day I began to have problems with seeing storms, so I started troubleshooting. Despite having the antenna in a plastic 10' downspout with a sealed top on it, the bottom where the cable came out was open and the humidity had been enough at times to cause the dreaded green creep to get all over the RJ11, despite the contacts being gold.
Any time you have current of any degree and moisture, there is the chance for problems.
With an hour's worth of time and some little dental tooth cleaning tools that my friendly hygenist had given me, it was nearly all gone and no vital contacts had been bent. I asked a couple local hams with eons of experience about it and they said to give it a little squirt with contact cleaner which would leave no conductive residue, and then gently blow dry with air from a can or compressor, then a SMALL amount of this dielectric grease.
I was aghast at putting that stuff in there for fear that if it were to get some conductivity that it, being close to silicone grease used in chem labs and such, that I'd never be able to remove it. However I do remember years ago installing hi band two way radio antennas on many many trucks, that we had a little packet from Antenna Specialists that was to be squeezed onto the contact from mount to screw on antenna coil and that always worked, so I did apply a teensy weensy bit with a toothpick and since then there has been good connection and last time I took the plug/socket apart, there was zero corrosion or green stuff and the gold contacts looked perfect.
Use it sparingly, but cover the areas needed. I see the folks at the semi maintenance shop using it on many of the 12v connections for lights, signals, indicators, etc. They say that with the amount of road salt and grime that those rigs see in a year that many of the connections look pretty bad in a short while, and where there are contact connections this stuff saves many hours of tracking down troubles.
Have fun.
Do you have your Boltek display on the web somewhere to show storms? Something we can click into to watch?
Thanks Dale
