Cable interference?

[dnd728]

I need to run a cat 5 cable for my network between two rooms. I wish to avoid the cables and the drillings, so I thought of running the wire through the holes where my TV antenna passes (hopefully). It's connected to cable TV, so I'm guessing it's not a faint TV signal. The length of the wire should be about 20 feet.

Should I expect any results? or is there no chance for this to work?

I'm going to need some gear in order to pass the cat 5 there, so I don't want to go throw all that in vain...

Any help/experience would be greatly appreciated.
Thanks in advance,
dnd

Hmm...I'm quite clear on this, but CAT5 Shielded STP is twisted so that it can block out interference. I'm am connected to a cable modem and I nailed my CAT5 network cable and phone line to the wall and just used twist ties to tie the RG6 cable to that. I'm not seeing an speed changes...so I guess it works. Hope this helps

CAT5 Shielded STP

Is that something special? Never built a network before...

STP stands for Standard Shielded Pair. UTP stands for Unshielded Twisted Pair. Taking a look at my cable, it shows UTP. It usually tells you on the side of the cables. If you've ever stripped a cable before, the pairs are twisted together. The reason they are that way is to shield out interference. I remember learning this before, but the knowledge is not too clear in my head. If you have any more questions, come back and post them...we'll be happy to help

Thanks ojai00!!!
I'll try that...

Just use standard Cat5 cable. You are not going to have any problems running it with TV coax cable. The coax cable is already sheilded and to prevent electrical interference from other sources. Also STP is harder to install correctly and it may even make the problem worse due to incorrect termination of the RJ45 ends.

Thanks!

BTW, true signature nightowl, and MacGyver once said - It's not the long fall that kills you.. It's the sudden stop!

STP = Shielded Twisted Pair
UTP = Unshielded Twisted Pair

In both cases, individual pairs of wires are twisted together inside the cable in an effort to reduce outside interference. With just a 20ft length of cable, you will probably not have any issue with good quality Cat5e UTP. Keep away from power supplies and fluorescent lights which produce electromagnetic interference.
