My installation company (a large one that works over the state) were very good. They got me to detail the issue and I included spectrum analyzer shots of the unit off and on.
Suffice to say they got nowhere with the brand head office, and referred the issue to Japan. The latter said words to the effect that trying to receive broadcast stations outside their broadcast area was problematic (even though my report was specific about the 2-20MHz range) and to check the house earth wiring (which was subsequently checked and fine).
The only issue the local company was aware of was potential TV interference if any brand's outside unit was placed below or in the vicinity of an external TV antenna, so they would always make customers aware of that when discussing a potential location. The fact that they work in regional areas where TV signals may come from sites some distance away may be an issue rather than in metro areas.
