A few years ago, I hooked up my security system to my detached garage. The security company had me run underground sprinkler wire(6 conductor?) to the garage. They hooked up everything - using only 2? of the conductors from the sprinkler wire.


Now I'm considering a Tv for the garage. Is it possible to use 2 of the unused conductors in this wire for Tv signal delivery?


My Tv cable comes into the house near my security box. It seems like I could connect a coax to a baluns? to the sprinkler wire in the basement and then do the same in the garage and get Tv reception.


If this is possible - would there be a problem with the tv signal interfering with the security system?

Yes, it's possible using baluns.

The picture will probably be pretty good if the run's not to long.

(Years ago on of the magazines [WSR] tried running video through an AC extension cord and it worked.

I don't think that interference will be a problem.


On second thought:

I'm not sure exactly what signal you plan to run.

If it's video and audio out of the STB - OK

If it's Channel 3 or 4 out of the STB - OK

If it's the cable signal before the STB - you may have limitations.

Speedskater - thanks for the tips


Whats a STB?


I'm rethinking my cabling idea. I just did some recon - I would have to do some work inside the security box and split off wires in a box they installed in the garage. Not really stuff I want to do. It'll trigger a call from the security co, and last time they were not pleased with me moving stuff around. I may just run a new line.


I may be able to split off a cable coax in my basement (at the garage end of the house), push a new line through the wall under my deck and around to the garage. About 200' of new line. It could be coax, cat5, whatever - I just want to make sure I have enough signal when it gets there

"STB" is the cable company's Set Top Box, That decodes their signal and outputs it as Chan. 3 or 4, HDMI, component, composite and other usable signals.


200 feet is a long way in a sprinkler wire.

Thanks - I dont have a set top box. I only have basic cable that came with my internet and it works without a box.

Usually a balun will work quite nicely on a TP line. However using a pair in a buried sprinkler cable and one also carrying a clocked signal most likely (for the alarm) will quite probably provide a very poor signal quality due to the proximity to water in the ground, close proximity to the clocking pulses, the fact that sprinkler wire is not twisted pair.

Thanks - I am rethinking this idea - I may scrap the idea since I only have basic cable anyway (for my internet - Directv is my main tv system and I don't want another receiver and higher bill)

Will your garage TV be HD? If not, you could do what you want pretty easily by running one coax line to your garage from one of your DirecTV boxes inside using a modulator and controlling your DirecTV box via RF. That would mean that you would have to watch the same thing in your garage as in your house on the TV connected to that DirecTV box. It also would mean that the RF signal would have to be able to control the box inside from the garage -- easy enough to test before you get started.

Don't forget to use direct burial rated coax if you do add anything. Nothing worse than having to re-do the job in a few years.
