Blonder Tongue Modulator, Multiple Units

[Arcanine]

I use an older AM60-550 for broadcasting a nice strong TV signal to my propriety. It makes using my old analog portables a complete and total delight.

I'm waiting to set up at least two more of these, giving different channel options to my TV's. Such as Consoles Games on one channel, movies on another, and rebroadcasted digital TV to another channel for news. That way I can just pop though channels on the analog sets and never have to disturb my transmitter to change what it's broadcasting.

These things are supposed to about 13mW, give or take to the antenna.

What I want to know is can I feed these units though a splitter in to a single antenna, or do I have to have an antenna for each unit?
