Homemade low power TV transmitter?

A combiner spliter will work just fine. Lets say you have an 8 port spliter you will lose about 11 to 12 dB going through it. Do you know what the output level of your modulators are? Most single channel CATV modulators will do +60dB.
It's all math you only need 0 to +3 at the back of the set. Each 2 port spliter you lose 3 to 4 dB.

Good Lock,
