I am attempting to connect my reciever to a second TV in another room. My first attempt was running coax through the attic from the RF out port to the RF in on the 2nd TV. This worked but the signal was very noisy.

My second thought was to run the actual component cables (red, white and yellow) through the attic and connect that way. Does anyone know if there are any sort of length limitations on doing this? It will probably end up being about 40-50 ft of cable.

Or if someone has a different apporach that may work better I would like to hear about it. Thanks.

I would check the ends on the coax cables. Running it 40-50 feet should give a good picture on the second set. You can run red, white, and yellow 50 feet but it is going to get costly.

Make sure the cable you are using is shielded... if you are going through your attic, you may be crossing electrical lines causing interference... moving from modulated composite to component will just change how the noise appears. I generally used Quad Shield RG59 in my town-house. Went hundreds of feed with loss ~1 dB/100 ft. I doubt distance has anything to do with it. Also, check your connectors... an air-gap between the end of the cable and the connector inside could act as a form of antenna - introducing more noise (i.e. similar to what HDMI Guy said). If you can use a pre-fab 50 ft cable, it might do you some good.

I agree with the other posters that you should be able to get a pretty good picuture via coax at that distance. Nevertheless, since you have a spare set of line outputs (red, white and yellow) you may want to try running them into an inexpensive modulator and send that signal via coax to your 2nd TV.

I've seen a pretty significant improvement in PQ via coax when using a cheap modulator (less than $20) as opposed to the one built into my DirecTiVo DVR.
