Although you said it's low priority, I'd like to ask if you're using a pre amp, what antenna you're using, and what kind of coax (RG6 or RG59) you're using. Make sure the preamp is getting power and that the antenna is aimed at the tri-point where Clinton Twp., St. Clair Shores, and Fraser meet.

It's coming in fine using a Clearstream 2Max in Melvindale indoors.
Not using a preamp, though I've tried using it. I'm somewhat close-in to WDIV, WXYZ, WWJ, WMYD, WTVS (& WHNE), so preamp provides way too much signal from the full-power stations, which causes its own set of problems. Antenna is XtremeSignal HDB8x screen 2x 4-bays with a hinged center, so one panel aimed toward Southfield, the other fairly accurately toward Clinton Twp., each panel supposedly has a 60˚ lobe so there's a bit of overlap. Using. Coax=RG6 approx 35 ft. Also combined into the array is a simple VHF dipole, for WJBK and CBET, which conveniently are approx 180˚ opposite each other. Hoping it will suffice for WHNE.
I'm a lot farther than you, and using cheap antennas.

What's the spacing between your antennas?? Is it possible you have some out-of-phase cancellation going on?

For WHNE, the elements will need to be a total of 8 feet, horizontally oriented.
