There are many reasons one might shoose to use RG-6. Take Belden 1694A as an example.
1. Once the cable is in place, it can be used for anything so it could be said to be more "future-proof". You can use if for long distance runs for composite video, serial digital video, cable TV, satellite etc.
2. There are RCA's that will work very well with it.
3. It can be terminated easily with BNC. You can terminate at a wallplate with a BNC and make a BNC to RCA cable for the other side of the wall plate if you need.

But you are right you shouldn't use RG-6 that is not meant for baseband? But what does that have to do with using RG-6 that is appropriate. All RG-59 isn't acceptable either.

RG6 and RG59 are simply form factors, RG6 is larger and has less loss at longer distances. Both varieties come as either copper clad steel or solid/stranded copper. You also have you choice as to the number and coverage of shielding. Solid copper is a better choice for lower frequencies such as baseband video or audio, copper clad is the more economical choice for higher frequencies above 5mhz. You can terminate either with BNC, RCA, or F connectors.

A tilt compensator will reverse the tilt of loss on a long run of cable. One hundred and sixty feet of cable does not require an equalizer for cable applications as your signal level requirements already have this built in per the FCC. Baseband video behaves in a much different manner, the above comments are all right, what should interest you is a good baseband video processor like the Elan piece. The Z880 is more than adequate for your needs for video distribution

I'm far from an expert, please do correct me if I'm wrong but baseband video (composite) runs around the area of 5MHz or less, right? While digital cable can reach upwards of 800Mhz. A tilt compensator is designed for equalizing those RF frequencies for TV channels....not composite video signals. What you'd need to send composite (Baseband) is something such as a distribution amp, mentioned above as the Elan I believe. If you're not sending a modulated RF signal, a tilt compensator is completely out of the picture. For Baseband only, I'd use a stranded RG59. Impedance wise, even professional BNC's have been 50 ohms for years, HD component and the new serial digital equipment is requiring 75 ohm termination and cable. HD signals themselves are still in the ballpark of 25MHz Alot of cables out there perform poorly at these lower frequencies. I'd only use RG-6 if you plan on changing things in the future to distribute modulated signals or Satellite IF signals. And as for the Audio, use a high quality shielded audio cable, the lower the impedance, the better.
