You must disconnect both the preamp from being inline and the power inverter.
We want the antenna coax to be directly connected from the antenna to the TV with nothing in-between (preamps, inverters, splitters).

My hunch is that with a rotor, you will recieve WRAL with the 4228 without the preamp. The 4228 has nice gain and WRAL's signal is strong enough for reliable reception. Your issue with WRAL and Raleigh is that you must be pointing that direction (magnetic 331) for best chance at reliable reception.

Due to the narrow beamwidth of the 4228, you will have to orientate it to the appropriate heading depending on what signals you want. One we establish stable reception, adding a rotor will give you ability to focus on each signal as you wish to watch them.

Also, I mentioned high-VHF. Do you want ABC WCTI (RF 12) Greenville, CBS WNCT (RF 10) Greenville and ABC WTVD (RF 11) from Raleigh? If so adding a high-VHF antenna to work in concert with your 4228 will likely yield you stable results of RF 10, 11 and 12. You may see them with the 4228, but results might be unstable due to the 4228 not being designed for high-VHF.
