Shreveport is about 90 miles to our east. Not too concerned about UHF interference from there.
OK. Then what is your nearest town?
FYI... It's not always about the station causing interference to you. You also don't want to be causing interference to someone trying to receive a TV station. The further away that station is the more likely that you can cause interference.
By law, you must accept any interference to your system. Also, you shall not cause interference to the reception of other licensed users, like TV stations. Without having a license to use these frequencies you have no recourse, or protection. The FCC allows you to operate without a license for 720 hrs/yr per frequency. That quite a bit of time, so most folks don't license UHF wireless gear. However, in an interference complaint the licensed operator always wins.
In the case of UHF wireless gear, and a first complaint, the FCC would likely just ask you to change frequencies. However, if you have multiple complaints, the hammer gets bigger, aka expensive.
All of this is why one should pay attention to where they are, and the frequencies they use. Set it and forget it doesn't always work, especially if you change locations.
