Default splitting cable signals....Speaking of AMPs

Just don't put the amp where there is little or no
signal or you


Speaking of amps .....
A couple of years ago we had 5 TV's and an amp, gemini I think.
We were eating dinner when we heard a loud beep, beep, beep
coming from outside. There was a Comcast cable truck outside.
The worker rang our bell. He said he detected an illegal condition
that needed to be resolved. If we refused, service would be stopped.
We let him in. He said that our amp was in violation and had to be
removed. We complied and he went away. The reason he gave was
that it interfered with aircraft, believe it or not. We never hooked it
back up. It was very scary to have somebody pull up outside and
"scan" our premisis. Makes you wonder what else they have.


He was checking for EMI,electromagnetic interference,and it's required by
Federal law.That's one of the main problems for cable companies,and they do
get fined by the FCC for it.They weren't 'scanning",they drive around with
a sensitive receiver with a directional antenna,that points in the
direction EMI is coming from. Loose or corroded F-connectors can cause
it,too.

One other thing,all amplifiers ADD noise to the signal in addition to
boosting the level.The cable companies usually deliver to the home the
lowest signal level practical to further reduce their EMI radiation.
