Television stations - 54 to 88 megahertz for channels 2 through 6
FM radio - 88 megahertz to 108 megahertz
Television stations - 174 to 220 megahertz for channels 7 through 13

Garage door openers, alarm systems, etc. - Around 40 megahertz
Standard cordless phones: Bands from 40 to 50 megahertz

Cell phones: 824 to 849 megahertz
New 900-MHz cordless phones: Obviously around 900 megahertz!
Air traffic control radar: 960 to 1,215 megahertz
Global Positioning System: 1,227 and 1,575 megahertz
Deep space radio communications: 2290 megahertz to 2300 megahertz
