FREQUENCY ALLOCATIONS
Because of the short-range nature of VHF and UHF FM communications, frequencies
allocated to services in one geographical location will not be heard more than 25-50 miles
distance (an exception is "skip" when signals bounce back to earth from the ionosphere). For
this reason a separate frequency directory must be complied for each local monitoring area.
Most standard frequency separations and classifications are regulated in the United States
by the FCC. Block allocations and even some discrete frequencies covered by your scanner
are shown below. These frequencies are not necessarily active in your area. Uniden provides
an eastern or western regional directory and a local listing of active frequencies.
Abbreviations
The following is a brief listing of the services
typical of the bands received by your
scanner. This listing can help you decide

In some large metropolitan areas, 1 or 2 channels of the
"TV Band" (470 MHz to 512 MHz) are used for
communication purposes. Each TV station (channels
14 through 20) utilizes 6 MHz.
470 - 476 T.V. Channel 14
476 - 482 T.V. Channel 15
482 - 488 T.V. Channel 16
488 - 494 T.V. Channel 17
494 - 500 T.V. Channel 18
500 - 506 T.V. Channel 19
506 - 512 T.V. Channel 20
Where
these
frequencies
are
assigned
for
communication purposes, in lieu of aTV station, the 6
MHz segment is allocated as shown herb for Channel

The same allocation pattern is repeated fpr each of the
TV channels 14 through 20. For example, if channel 17
is assigned for communications in your area, "Taxi"
would be 490.3625 to 490.4375 arid 493.3625 to
493.4375 (corresponding to 472.3625 td 472.4375 and
475.3625 to 475.4375 above). Note that in the example,
we added three TV channels (18 MHz to the channel 14
frequencies).
