I have a Jayco Eagle 2017 29.5BHDS.
When watching TV, with the antenna, and we turn on the Bathroom exhaust fan... it significantly interferes with the TV reception. Assume the wires must run in the same proximity? Anyone else have this issue? Any suggested resolutions?
Mine did the same with the OEM fan. The interference stopped when I replaced the OEM with a Fan-tastic Fan. Probably something to do with the much lower RPMs the Fan-tastic runs at. Maybe put one of those magnetic (ferrite) rings around the antenna cable to reduce the EMI? Really not sure, just spitballing here... Probably need a EE to chime in.
Try connecting a 0.1 µF ceramic capacitor directly across the fan motor. Keep the leads as short as possible. This should minimize any interference caused.
