Signal loss with longer RCA cord? (25 feet) (for people who have tried it)

[SearsRoebuck]

I've been looking around the internet and found a few different takes on this, so I am wondering if someone who has actually tried this can tell me what your results were.

 

My set up requires me to have my CRT about 25 feet (in the same room, cord wrapping around the room) from the switch box where the systems are. I'm wondering if there is going to be any substantial signal loss with such a set up? Some other forums I've looked at say that it may be noticeable until you start going past 100 feet.

The better shielded-cords will go farther without loss and/or interference. High quality coax can go a lot farther than a thin two-wire RCA cable, for example. Really cheap wire can suffer significant loss even if it is very short.

Stick with true 75ohm cable and you should be good. If you see too much interference, can simply purchase a signal booster. Switch boxes can be a source of a lot of interference actually, so make sure your connections are good, switches are clean and the box in general is not a rusty pice of crap.

Just so everyone is aware, he is specifically speaking about composite video signals here not coax.

I run composite over a subwoofer cable (bought this because I thought it had more shielding) to my projector, believe the cord is 25 feet or 50 (it's in the ceiling and I ran it years ago so not sure). I've never had any signal issues.

Yes, and I use a 75ohm RCA cable (originally meant for component YPbPr) for the systems I have modded for composite. Gives a better picture and is less susceptible to interference. Can also purchase coaxial to RCA adapters on the cheap if you already have some good coax cable laying around.
