Commonly Used by Federal Agencies for Bugs, Wireless Microphones,
and Body Wires (power output normally below 5-50 mW).

Also, Wide Band Frequency Hopping centered on the video signal of
UHF-TV channels
(i.e.: 510 or 670 MHz with a hopping width of +/- 25 MHz)
Keep in mind that the federal government can use virtually any frequency between DC and light.
