| old cable outlets with resistors
does anyone know the tecnical term for outlets from the '70s that were put in a single gang box and uses a power outlet face plate.
one side of the outlet is fake and the other side has the cable outlet in it.
the back side has a resistor on it. what was the purpose of this resistor and will it effect the picture if not replaced? |

@comcast.net | That is a self terminating wall plate. Not necessary what so ever, replace with whatever you would like. I'm not even going into what it does as you shouldn't worry about it at all. |

You can take the resistor out an use the outlet that way. They use terminators so there no leakage of signals. Don't take out resistors unless you going to use that outlet.

some mispelling in there......Caddyroger
so i can use these plates with the resistors still on them or buy new ones ?
you said take out resistor and the next sentence wasnt too clear.
thank you for your help .
also.....thank you "trythisfirst" but can I use them as is with resistors intact. sorta sounds like it couldnt hurt anything right? |

On the outlet you are going to use put in a new plate. Do not use the resistor. On the outlet that you are not using leave the resistor on it. This prevents leakage of the signal.

What you have sounds like an old wall plate for OTA signal from an antenna. Best bet would be to replace the wall plates with updated ones. This would eliminate any possibilities of potential issues you may run into with using those antiquated wall paltes. |

Pottsville, PA | I was thinking the same thing as wanger...and if we are correct, the cable running to that outlet will need to be replaced. |

Actually these type outlets most likely are not "self terminating" - what they actually are are called "line tap-off" outlets. (also known as series loop outlets) These were used in many MATV systems - instead of home running every outlet back to a central point, you simply took your main coax trunk & "looped" it from outlet to outlet. The resistor provided isolation between the main trunk & that individual outlet, similar to the way a splitter works.
Here is one such outlet, which is probably similar to what you have now:
»www.winegard.com/offair/outlets.php
(look at the ST-7700 outlet, which is the first one posted here)
Are there 2 cables going into this plate? Are you in an apartment? If so, you probably should leave things alone, as you could mess up signals for others in the complex. Some complexes, particularly that have bulk arrangements w/the local cable co, still use these even for the current cable signal. |
