RF Modulator Question

Hi Gents,


I have a question about using a RF Modulator in order to convert
S-video output to RG6 compatible.

Well I want to carry out my video signal over 200 meters (~656 feets)
where my tv is only compatible with RF input. To do this i am planing
to use a RF modulator which converts my DVD's s-video output. Distance
between my DVD and TV will be approximately 200 meters.

Does this infrastructure work?
Do you have any additional comments in order to carry s-video signal
with coaxial cable over 200 meters?

Thanks,

Antonis..
