Hello, ERINLAINE
The signals at each of the four outputs will be approx 8 dB stronger than when they entered the distribution amp, whether a TV is off or on.
If one of the output ports isn't being used, there might be a slight unbalance as there is with a 4-way passive splitter. Putting a 75 ohm termination resistor on the unused port will restore balance, but it isn't critical.
That is why good satellite splitters come with a termination resistor for each port.
If you have a 3-way split with one run much longer, this is an efficient way to do it:
