Will Coax interfere with ethernet?

[futonpimp]

If i run coax lines alongside ethernet in the house..will they cause interference with each other?


Thanks in advance.

Not at all.

thanks Tim

Um, don't tape them together. The outside of a coax cable is grounded, and will attenuate the ethernet signal if they are tied too closely together for to long.

Are you sure? The outside of coax is a plastic/pvc coated jacket. The ground braid is inside the jacket.

Plus if your theory was correct, why would they sell structured cabling?

Yes, I'm sure. The shield is ground. The ethernet is high freq. You take 2 pieces of metal, run them near each other, and you make a capacitor. Capacitors act like shorts to higher freqs. The real question should be how long you can run them together. Few feet, sure, a few yards, maybe, more ...

Ever heard the term, "There's a sucker born every minute"?

The shield is ground, but the shield is inside the outer PVC jacket. PVC is non conductive. Check your research.

Both the Coax and CatX have PVC jackets, which is an insulator. The shield for the Coax is beneath the PVC jacket. Running these two together won't cause any problems.

And what do you think the dielectric in a cap is made of, a conductor????

A cap is ANY 2 conductors with a insulator in between them.

The electric potential required to pass through ~1.5mm of PVC is much larger than the potentials dealt with in these applications.

Think its time to lock this thread?

I'll ignore it if you will. Let them have their fun.

well I dont know if hes completely right but see where he would say this

but im gonna run my cat5 cable anyway and hope for the best cause some crosstalk would just mean i wasted 8 bucks and need to pull my wire back out. So i say "big deal" in my case.
