[SBE] OTA digital TV interference

[George J Molnar]

When I was Chief at a station in Chicago, we saw both train (“L") reflection and pulse noise from the electrical system as interfering possibilities. Especially where the tracks were reasonably close (say in direct sight, and between the RX and TX).

Filter unlikely to help, sadly. Only better antennas & feedlines,

For apartment buildings especially where antenna height is not an option, if that would fix the problem at all.  Can a filter be installed between antenna and TV that would help to remove what I think is EMI coming from the trains?
