Re: RR's RCA Fried Me!
Your cable franchise will either:
a) laugh at you
b) be very sympathetic
but in either case, they are not liable. If lightning strikes the pole outside, that's considered an 'act of nature' - nothing they can do to prevent it. Same thing would be true if the lightning travelled down your electric wires and blew up your TV/Computer(s)/etc, or hit the telephone wire and blew up all your phones.
For this reason, many UPS units, and slightly more expensive surge protectors (electrical) now include surge protection outlets for telephone lines - and ones intended for home theater include co-ax connectors for cable/satellite.
Good luck in trying, though - just don't expect to get anywhere.
"Q: When will it be done? A: When pigs fly! "
Hey dBm, as every tech I've ever had in my home takes any splitters or surge protectors out of the loop, riddle me this:
what SHOULD my levels be coming INTO my house from the main feed?
what should my levels be on each one of the drops coming out of the main splitter-who-gee on the side of my house? what should my levels be coming out of the wall?
I don't know what to do when a tech insists my $100 surge protector cannot be in the loop, or a 1 or 2 gig splitter on a four-foot run nukes the levels. I can either allow them to take it out of the loop or wait for them to re-wire/re-balance the whole neighborhood, correct?
You asked a clear question - it's the answer that is muddy.
Immediately downstream of an amp in the hardline the high channels are set to a higher level than the low. This is because coax attentuation is higher for higher frequencies.
By the time you get to the next amp the opposite is true.
So, amp spacing is governed not only by the average loss in the coax but by the allowable tilt, which is the ratio of the high channels to the low. Now, at your particular tap, the tilt can be either direction, and the level of the channel carrying your downstream can vary greatly.
Having said that, a cable company might shoot for + 10 at the tap, less the loss in your drop. If they get an unacceptable level at your house, their alternatives are to adjust amplifier gain which is scary because it affects so many users. The other alternatives are to change out the tap or change to RG-11 for the drop and reduce the loss. If they change the tap, they may need to add attenuators to the other houses fed from it.
High signals aren't a problem. Just add an attenuator or change out the splitter/directional coupler at the separation between the modem side and the tv's.
As for removing your splitter or surge protector, please remember that it is their signal and they don't want to be accountable for problems associated with your equipment.
