Most of the channels you want are from Hartford and are strong. You can get them with a UHF antenna like an Antennas Direct DB4e or C2V and no preamp. The C2V is being replaced with the C2MAX. Add the accessory reflector if you get the C2MAX.
The problem comes with ABC. You will need a separate antenna for ABC and a preamp.
You have the weak WGGB in Springfield, now on UHF real channel 40, but moving to channel 26 during Repack Phase 8, 1/18/2020 to 3/13/2020.

You also have the weaker WTNH from New Haven on VHF real channel 10. It will require a separate high gain VHF antenna like the Stellar Labs 30-2475 or 30-2476 and a preamp.
You will have to do some experiments to see which ABC you can get, and then figure out a way to combine it with your Hartford UHF antenna.
How many TVs will be connected to the antenna?
If you want me to study the problem further, give me your exact address and coordinates in a PM to protect your identity, and I will look at the signal lines in a satellite view.
