I know some of the HOA Nazi's in Tucson actually use field-strength meters to detect stealth installations...one notable HOA near my UNRESTRICTED QTH actually spells out the only LEGAL transmitters: Baby monitors, cordless phones, cell phones, bluetooth, 802.11x devices, to name some..as well as the usual spurious devices. And, they put aluminum sheeting on the roofs (under the shingles) to prevent attics being used for stealth antennae. Wonder if they actually discourage licenced hams from purchasing a home in those subdivisions???
