You have one very strong FM transmitter that might interfere with TV reception. See attachment. If it does, insert an FM filter in the coax line after the antenna. If you use a preamp that has an FM filter, that might be enough. If not, insert the filter between the antenna and the input of the preamp.

A UVSJ (high and common ports) can be used as an FM filter instead of a regular FM filter when you only have UHF channels to receive.
