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

rather
be complaint driven instead. They also use circulators so that the
stuff
people do in their house doesn't feed back into the system and screw all

other customers up.
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.
