Tv antenna rotators Are Not Channel Surfing Friendly - must wait for antenna to rotate and there Will Be Domestic Issues about the direction the antenna is aimed.
The RCA ANT3038XR antenna is a Big Highly Directional antenna that is not a good choice for reception at your location.
_____________________________________
To get the best reception of the Digital Broadcast Tv stations/channels using the ANT3038XR antenna of the Tv stations to the , west ->WTIU-DT PBS and from WTIU going from WTIU , clockwise to the , north ->WNDY-TV MyNetwork and the Tv stations in between those 2 Tv stations.
Aim the ANT3038XR antenna at about 330 degree magnetic compass direction.
Here is how to aim antennas ,

As always the starting antenna aim direction is the --> starting antenna aim direction.
The aim direction can be adjusted for best reception.
Most digital Tv's have a signal strength meter and some digital Tv's also have a signal quality meter.
______________________________________
Also as a -Test- to Prove Reception by Eliminating active and passive devices that can cause trouble with reception.
Disconnect and Remove All parts of the AP8275 Preamplifier , Remove the preamplifier unit at the antenna , Remove the power injector , Remove the power supply. Actually disconnect and remove so there is no temptation to connect it in any way shape or form.
Replace the matching transformer (balun) at the antenna and connect a New coax to the New matching transformer and run the New single long continues length of coax through a open door or window to 1 Tv.
No grounding couplers , No couplers , No splitters , No passive or active devices.

Tv tuners can develop - Digital Glitches - that are not cleared out with simple channel scans.
Do a Double Rescan ,

What Tv stations are and are not received now??
Are the channels your are having problems receiving , received now??
Is the weak signal strength WNDY received??
Is WTIU received??
((Best reception means , aim the antenna to find the best reception at one direction and leave the antenna aimed at that direction.
Do not keep rotating the antenna to improve reception on different Tv stations channels.))
The idea is to improve/eliminate issues that cause problems -> to certain point.
Not create more problems.
What is reception like now??
