You are maxed out with the home made antennas.
Time to move up.
The Current Broadcast Tv stations/channels in , USA , Canada , Mexico , are.
VHF low band channels 2 thru 6.
VHF high band channels 7 thru 13.
UHF band channels 14 thru 51.
Your location has channels in all three channel bands.
Most of the signal strengths at your location are Weak Signal Strength.
Concerning WMC-DT Real channel 5 NBC is , low signal strength , 2 edge path obstruction , and 66.2 miles away to the South West.
Low band channels are effected more by interference.
I can not say reception will be reliable even with a Big antenna.
Time for a BIG All Channel Antenna.
Above The Peak of the Roof in such a manner that reception is not impeded and blocked by the roof and house in the directions of , South West , South , South East.

The Tv/s Must Channel Scan for the , OTA=Over The Air , Digital Broadcast Tv stations/channels , often named the 'Air Channels' or 'Antenna Channels' in the Tv Setup Menu because the Tv transmissions travel through the Air from the transmitting antenna to the receiving antenna.
Some Digital Tv's will Automatic channel scan for cable tv channels.
DO NOT channel scan for cable tv channels.
Go into the Tv Setup Menu and select 'Air Channels' ~ 'Antenna Channels'.
Digital Tv Tuners can develop - Digital Glitches - that are not cleared out with simple channel scans.
Do Double Rescan ,
