There is only -->1 preamp<-- and it is connected to output of the UVSJ.

THE ANT751 is connected the VHF connection of the UVSJ and the DB4e is connected to the UHF connection of the UVSJ.

That leaves 1 more connection on the UVSJ the third connection/is the output connection of the UVSJ and the -->1 preamp<-- is connected to that.

Use only a UVSJ to connect the ANT751 and DB4e antennas together , DO NOT use a common simple splitter in reverse to connect the ANT751 and DB4e antennas together.

_______________________________________________________

The CPA-19 preamp has 3 parts , the actual preamp that is mounted close the the antennas.

The power supply and power injector.

Power from the power supply and power injector flows through the coax to the preamp so the preamp has power to do it's job and amplify.

__________________________________________________________

If more then one Tv is connected,

If the power supply and power injector is connected to one of the outputs of a splitter then the splitter must be the type and kind of splitter that will pass power through the splitter to the preamp.

________________________________________________________

Or can put the power supply and power injector on the input side of a splitter , in this case the power is not going through the splitter. And because the power is not going through a splitter then the power flows through the coax that the preamp is connected to.

________________________________________________________

If 1 Tv is connected then no splitter is required. And the power supply and power injector and preamp will all be on the same coax so nothing will interupt the power to the preamp.

__________________________________________________

-->The Point Is<-> power needs to get from the power supply/power injector to the preamp so the preamp will have power and can do it's job of amplifying the signal.
