OTA Antenna - Where to put splitter

[bunker]

Right now, my antenna is in my attic, with about an 80 foot run down into the basement then up to my TV on the main floor.
It has a pre-amp and the power supply for that amp is plugged in at the end of the run, right before the TV.
I want to split it so I can run the antenna to a bedroom.
My question is, where does the splitter need to be in relation to the power supply?

Right now:
Antenna-->Power-->TV

Proposal A:
Antenna-->Power-->Splitter-->2 TV's

Proposal B:
Antenna-->Splitter-->Power-->1st TV
Antenna-->Splitter-->2nd TV

Since I can't really draw here in Prop B the 2nd TV would come off the same splitter as the first.

I'm assuming Prop A is correct, but my google skills are failing me.

When I was using a powered antenna in my attic going to two rooms, I was using "Proposal A" and didn't have any issues. Unless of course I removed the powered part and then I got no reception. I'm wondering if you would get good reception on 2nd TV on Proposal B.

Antenna --> 50' run to Power --> 50' run to each TV

I now have a bigger antenna that isn't powered but pulls more stations

You can also split the signal before the pre-amp's power injector if you use a splitter that has DC pass through on one of its ports. A standard 2-way splitter will work best if placed after the power supply (Proposal A).

A pass-through splitter gives you a little more flexibility on where you can place the splitter. This would be Proposal B. You just have to make sure that you place the pass-through branch on the line that goes to your pre-amp's power supply.

Prop A is the better option and will result in the cleaner signal.
