I could also buy something like a db4e or ab8

I have both the DB4e and DB8e. You can't go wrong with either. The DB2e might also work. You may need the VHF kit, but I'd try one without it.

You should be able to get away with something like an Antennas Direct DB2e, or an Antennas Direct ClearStream 2V.

Also note that the majority of channels are UHF.
