Another (perplexing - at the time) dispatch involved a simple, plain-old CATV leak -- but it was mid-span on the overhead wires! Binoculars confirmed that some squirrels had eaten clean through to the inner conductor.


Rodent damage to CATV hardline more common than you would expect. Especially in colder climates. It was a big problem for us, near Cincinnati, back in the '80s.

Many power and phone poles have required replacement, since the little rattlebrains pound away at the tops of the poles, until they work their way down to the through pole hardware. It was worse on the old creosoted poles than the pressure treated poles that are in use, today. They destroyed a full foot of the pole at my previous home, until the anchor to the guy wire broke free.

Rodents - as a group - have incisors that keep on growing all the time, and have to be ground back by chewing on stuff to prevent them getting inconveniently long.

Rodents aren't famously communicative, but people who study them do report their results, albeit not in places that serve up enough extra flattery to interest John Larkin.

Our .750 and .500 hardline was unjacketed. Jacketed cable was generally used in high salt areas, like near the coastlines. Just an aluminum tube filled with plastic foam, and an aluminum center conductor. Tell me what that tastes like. If they don't chew enough hard objects, their teeth continue to grow until they can't eat.

Indeed. If you felt better about yourself you wouldn't need to be obsessed with assigning fault to so many others.

Mike, if you only read your posts as if they were someone else's you might realize the mental state you have. I'm not even sure how to describe it. It's all about negativity and intense criticism of anyone who doesn't agree 100% with what you believe. I don't mean you disagree with people. I mean you can't disagree with people without calling them names, i.e. ad hominem attacks and just being mean.

I guess I should just ignore what you post and let you rant away in your world. It's not like anything I say to you will ever have any positive impact.
