The Antennacraft 10G202 is a high-gain amp that is relatively easily overloaded. AC's own website includes this advisory: "Best used in deep fringe areas where all signals are weak."

See post #2 for appropriate recommendations.

No, no aircraft to cause the issue.

I don't have your exact address, but I think this FMFOOL report is more accurate than a zip report. It shows WBHQ 92.7 MHz 2.1 miles away at -18.4 dBm; attachment 1. I think an FM filter is called for to prevent interference, even if your preamp has one.

The RCA and the Juice preamps are more resistant to overload than the Anntennacraft 10G202. The RCA has an FM filter, the Juice doesn't. Put one or two in series between the antenna and the preamp input. Your strongest FM signals are 92.7 and 98.7 MHz. All FM filters are not equal (see attachment 4), but you have a choice based on those frequencies: Antennas Direct, MCM, and Radio Shack.

You can also use a HLSJ as an FM filter, connecting to the high and common ports. It rejects everything below CH 7, including the FM band and has low insertion loss:

And I see a lot of trees, which are the enemy of UHF signals; attachment 2.

scroll down to Trees and UHF

And I see a highway that the signals have to cross; attachment 3.
(I also see an airfield, but we covered that.)

I am aimed at about 165 degrees (pointing south) I am just using an iPhone compass and standing under the antenna to guesstimate the placement.
176 magnetic with a real compass would be better.

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, but the system will not survive a direct strike.
