In Reply to: Video Distribution using RF Modulators? posted by Dave T on April 10, 2000 at 00:00:45:
Thats pretty much your options- using a commercial unit. Modulators are avaliable at Radio Shack, but, only output on channels 3 or 4. Otherwise using a commercial unit (agile modulator they are usually called)to get other channels. P.S.- do not allow your modulated signal to back feed to the cable company feed. They will get real upset about that!
Brian, or anyone....I have one of the Radio Shack RF Modulators (model 15-1244) to transmit my DVD to the other TVs mentioned in the main subject. It works great! It only transmits in mono but that's what the bedroom TVs are anyway. The problem is that it ONLY transmits on channels 3 & 4. I'm looking for a programmable one that will transmit on channels around 100 or so. I'll need to transmit 4 devices on different channels. I know that once I've found one I'll have to install a channel block (low pass filter) to avoid "backfeed" to the cable company. I've found some low pass filters for around $20.00. Do you know of any other brands or sources other than Channel vision or Channel plus? I like to comparison shop. I've only found smarthome.com as a source.
Try starkelectronics.com for starters.Price may not be to your likeing as most "agile modulators" are made for the cable tv industry and are "industrial quality" so the price reflects it.
