First, I hooked the Polaroid up and pointed towards Johnstown; approx. 150 deg.
Picked up WJAC (UHF) but not WWCP (VHF).

That is to be expected. The Polaroid isn't very good for VHF.

Anyhow, I took it (DB8e) off the metal roof and put it on a wood light pole.
Right now, it's 10' up to the center bar.
I had some mixed results with just the antenna.
Then, I tried the RCA preamp.
I got nothing at all with it.

You changed two things at once, so you can't be sure which one caused that result. You moved the antenna AND you added the preamp.

Is the preamp the RCA TVPRAMP1R?

I am using one with my indoor antenna and it works OK. It is inexpensive, but that model has a history of quality control problems. One of the problems is with the power supply. Amazon is selling it as a warehouse special, which is returns that they are reselling, but they are not testing them; the power supply is often dead.

Another problem is with the combined/separate switch. It usually works OK in the combined position, but if the switch is moved to the separate position for separate UHF and VHF antennas, it doesn't always make good contact with the VHF antenna.

This particular pre amp seemed to not work.
There were no instructions but I hooked the antenna to the UHF/Combined port.
There was a switch that I left on.
The other choices were FM Trap and Off.
I don't know what to make of that.

You should have received instructions with it.

However, when I hooked UHF and VHF back up to a splitter, that dropped to 5.
I am waiting for a combiner to come Tuesday.

Seems like the splitter I'm trying to use as a combiner doesn't work for UHF.
It has no affect on my VHF stations.

I don't quite understand what you did. If you connected a UHF antenna and a VHF antenna to a splitter to combine them, that is the wrong device to combine a UHF antenna with a VHF antenna. Tell me about the splitter.

I am waiting for a combiner to come Tuesday.

What combiner did you order?
