Projector Help

Hi All,

(Hopefully) a quick question. I just purchased a home that was pre-wired for a theater in the basement and I'm looking to hook up my projector. There are no terminations on any of the wiring - just a large run with 6 rg59 coax cables and a cat 5 run. I need to set up video component wiring due to my AV receiver not accepting HDMI. I've tried to run compression RCA's off of the red/green/blue wires but cannot get a signal to process.

Any suggestions on how best to terminate the rg59 on either end? Thanks for any and all input...

I'm 99.999% sure you are going to need to run component cable as RG59 and Cat5 are not capable of handling the signal. I have heard of folks making various analog cables out of Cat5 however but you would need 3 Cat5 runs for this.

If anyone has managed to find a workaround I am sure they will speak up soon.

Good Luck

Re: Projector Help

Keith,

The RG59 cable is almost useless. RG6 is standard. RG59 is generally only used for audio cables now, not video. The Cat 5e cable can be used, though. You will need to purchase Cat 5e to Component Video Baluns. They are very common and many companies make them now. Basically, they are converter boxes that convert that Cat 5e cable to component video cables.

Huh???
RG59 vs. RG6
RG59 is perfectly fine for component baseband video, it's used all the time, if you google for RG59 component video cable you'll get a zillion hits. Just a matter of terminating things properly. (Sorry I don't know details of this.)

What you don't want to use it for is long runs from satellite dish to receivers, or for CATV distribution when using high frequency bands for HSI or digital TV, where you need RG-6 to reduce attenuation.

A small correction - RG-59 has more than enough bandwidth to carry satellite signals. It has a smaller center conductor and there is a voltage loss going back to the dish or switch and that is why RG-6 is recommended for satellite installs.
