Welcome back, k man:
I see you are going to give ABC another try. Jake is right; you need to try some of the ideas suggested in your previous thread to improve your reception of ABC. I favor something like Jake's idea No. 2 for WTNH, because if you try for WGGB, it will be difficult to combine two UHF antennas without a custom combiner. Both are very weak, but WTNH is on VHF-High channel 10 so it will be easy to combine the two antennas with a UVSJ UHF/VHF combiner.
You shouldn't need a preamp for your first 5 UHF channels, it would probably be overloaded by WFSB.
The MCM 30-2475 or the higher gain 30-2476 would be a good choice for WTNH. They are inexpensive, have poor assembly instructions, but usually perform well.

The antenna should be aimed at 195 degrees magnetic with a compass (182 degrees true).

You have some strong local FM signals that might interfere with the reception of ABC and will need an FM filter. You could use the Antennas Direct FM filter, but I think a HLSJ, high and common ports, would give more rejection of WCCC-FM on 106.9 MHz.

the HLSJ blocks all signals below channel 7, including the FM band

Use high and common ports of HLSJ to pass VHF-High and block FM
The coax should be grounded with a grounding block to help reject FM interference.
If the antenna is outside, the coax shield should be grounded with a grounding block that is connected to the house electrical system ground with 10 gauge copper wire for electrical safety and to reject interference. For further compliance with the electrical code (NEC), the mast should also be grounded in a similar manner to drain any buildup of static charge which will tend to discourage a strike, but the system will not survive a direct strike.
