Rg6 coaxial cable vs utp cables
Rg6 coaxial cable vs utp cables
(OP)
Hi I just recently found out that we can use utp cables for our cable tv system, we'll just have to buy the proper termination kit, balun to filter.
- Is utp cables less prone to interference than shielded coaxial cables?
- how does the Balun works?

RE: Rg6 coaxial cable vs utp cables
For cable TV? Crazy idea. Forget about it. Nobody does it. Even if you can get it working, it would not have any advantages over coax.
PS: RG-6 (well shielded, 2.2GHz rated) is about Cdn$60 (~US$50) for a 1000-foot roll. The connectors are a bag of 100 for maybe Cdn$12. It doesn't get any cheaper than that.
In answer to your questions:
- No.

RE: Rg6 coaxial cable vs utp cables
Whenever you have a tranmission line, it is necessary (or at least a very good idea) to terminate it with a value that is equal to the Characteristic Impedance of the transmission line. This prevents intereference from reflections caused when the transmitted signal impinges on impedance at the end of the line. That is the purpose of the balun; to provide impedance matching between the two tranmission lines - much like 75 / 300 Ohm transformers.
