I don't know if you have seen CATV hardline with a tank strapped to the

be complaint driven instead. They also use circulators so that the

Ever open up a cable amp that has had leaky (water type leaky) coax
dripping into it? Yikes, they usually keep working for a while, with all
kinds of electrolyzing going on. It's a pretty sad sight.

I've seen boxes of them. I wish I had pictures of the Micor mobile that was
parked in a supervisors car in the middle of a river for 3 days. The
battery went dead making green slime. The only money they had in the budget
was for repair, so we bid them to replace every board. The Mastr Exec had a
Relay and worked fine after drying it out. Things like that are hard to
explain.
