HTD Posted September 20, 2008 Posted September 20, 2008 I need to split composite signals from a DVD player. I'm going to be running rg59 10m from the DVD player to two TV's. I've done this before using a RCA splitter. But I want something more substantial can I use a 5mhz to 1000mhz splitter (FTA splitter) or is composite on a really low a mhz. I thought it was 4.5mhz. I've seen BNC splitters so they might have to do.
digitalj Posted September 20, 2008 Posted September 20, 2008 what about modulating the composite signal to an RF Channel, and splitting this?
HTD Posted September 20, 2008 Author Posted September 20, 2008 what about modulating the composite signal to an RF Channel, and splitting this? Would rather keep the DVD on the AV inputs. If my cable run was longer I would.
Rusty Juggler Posted September 20, 2008 Posted September 20, 2008 I need to split composite signals from a DVD player. I'm going to be running rg59 10m from the DVD player to two TV's.

I've seen BNC splitters so they might have to do. The only proper way of doing this is using a video distribution amplifier, a 5-1000MHz splitter won't work as the composite signal really is DC to 5MHz. Using an RCA T-piece will half your video amplitude (the brightness will drop significantly) as both TV's terminate the line with 75 Ohm. You can, of course, remove the 75 Ohm resistor on one of the tele's video input, making it HiZ but I wouldn't recommend it! What about audio, are you splitting this as well? Cheers Rusty

Cheers Rusty No not splitting audio. What about a dc splitter? with power pass both legs
bellotv Posted September 20, 2008 Posted September 20, 2008 just use ther RCA splitter as you have in the past ,sure its not technically correct but it will work.You may have to fiddler with contrast /brightness on each TV but it will work.You are correct that the signal is lower than 5MHz. so don't use the 5-1000MHz splitter ,it is designed for splitting RF as Digitalj suggested.There are Base band video splitters available as used commonally in the security camera industry but the RCA splitter will work if you want to save a buck
