Hello, Dave; welcome to the forum.
I see you are now able to post. Your report is only resolved to block level because you left out the W in your address. With the W added, it looks like this:

NBC is no longer on WMGM, so you need to find a different channel for that.

WWSI is your strongest NBC, but it is to the north; most of your networks are SW.
You might be able to get everything with a UHF antenna aimed SW:
WMDT ABC, 232° true, 244° magnetic
It will be moving to channel 29 because of UHF Channel Repack:

WRDE NBC/MyN, 217° true, 229° magnetic

WBOC CBS/Fox, 229° true, 241° magnetic
It will be moving to channel 32:

I suggest an Antennas Direct 91XG or Solid Signal HDB91X antenna and an Antennas Direct Juice preamp. No guarantee, because your signals are weak.
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.
