I live in a single family townhome (house with lots of HOA rules) and a fan dipole in the attic. With the dipole oriented NW-SE, it was right over my radio controlled garage door opener. Operation at 100 watts on any band would turn on the light, but on 40 meters the door would try to go up and down with my CW keying. The wiring to the opener couldn't be worse from an RFI standpoint - two wire unshielded all over the garage walls and ceiling. I wound up with what we call the trivial solution in math - moved the dipole to NE-SW and now 40 meters only turns on the light. Not sure what there is about 40 meters but that is also the only band that caused a little TVI on one of the TVs as well. The XYL was not amazed! Similar lack of humor to when I had a SB220 linear running parallel 450 feed to a G5RV and turned the call ID units into French! Instead of "unavailable" it came up with "hors de ????". Sold the linear and went back to coax.
