In this install I'm doing we've got RG59 wire run throughout the house. Reception of the highest cable channels is weak already but I'm hoping to hook up a 4 channel modulator. We've got 2 security cams and we need two video sources to run to the 7 or so tvs in the house. I have 2 questions:
A) Anybody have any tips on getting the best performance out of this old wire? I might be able to run some 6 wire to the furthest point but I'm not going to be able to do anything with some of the other runs.
B) I need a dvd changer that has big on screen displays of what it is doing. The main purpose is as a cd player but with the modulater I'd like to use it as a dvd player as well. So far I've looked at the cheap panasonic and Sony stuff. They both display the info pretty small and don't seem to show all the info anyway. The idea is visual feedback so the customer can see what he's doing when he's pressing the remote control buttons (niles component commander with ir sensors in each room).
Thanks alot for any help.

Look into amplification w/ tilt compensation.

That's what I was thinking. Any suggestions on models? I've noticed that kind of thing on VGA amps but I haven't seen any rf amps yet that claim to have tilt. But, I'm not terribly familiar with all the video brands and models.
Thanks

Typically tilt compensation is handled w/ an outboard filter. I do know the Channel Vision CVT35IA has onboard tilt.

I have used the channel vision piece myself and from what you are describing i think it is just what you are looking for. It has onboard adjustable tilt comp plus onboard up to 35db gain.

I was ready to just get a channel plus tilt compensator and a 506bid amp. How might this channel vision unit compare?

Yeah, you can just use brute force and amplify the heck out of the signal. Five years ago I fixed NEW HOUSE that had three floors of RG-59, with each floor wired in a six-outlet daisy chain! Just amplified the signal about 30 db, then used directional line taps at every outlet. We had so much amplification that we did not need to worry about tilt.

Outboard tilt compensators work pretty well, and even better if you can measure the signal loss and figure out how much compensation you need. Pico/Macom and others make them. If you use an outboard compensator, your amp choices will not be limited.

Tilt compensators attenuate lower frequencies so they match the levels of the upper frequencies, which are attenuated in the cable, better. The tilt compensator should go after the amp, not before it, for lowest noise.
