please provide sources
I need a long cable run and it needs to go through several walls maybe 250'
Thankyou

I believe you'll be able to run about 50' of cable max before the signal starts to deteriorate, so perhaps you could run cat6 or something instead?

Search google for component video baluns. I've always had good luck with niles baluns. If you run 3 coax for video you can get all the tools and the ends at many home improvement stores or off amazon.

RG6 compression rca ends can be had on amazon for like 1.50$ each (need 6), plus the compression tool, plus the cable as you Would need 750' for 250' run of component. you are much better off with the baluns and the cat5e or cat6.
