Sec. 87.421 Frequencies.
The Commission will assign VHF frequencies after coordination with the FAA.
Frequencies in the following bands are available to control towers and RCOs.
Channel spacing is 25 kHz.
118.000–121.400 MHz
121.600–121.925 MHz
123.600–128.800 MHz
132.025–135.975 MHz
(a) The frequency 123.100 MHz is available for use by control towers and
RCOs at special aeronautical events on the condition that no harmful
interference is caused to search and rescue operations in the locale
involved.
(b) Frequencies in the bands 200.0–285.0 and 325.0–405.0 kHz will normally
be assigned only to control towers and RCOs authorized to operate on at
least one VHF frequency. The Commission may assign frequencies in these
bands to entities that do not provide VHF service in cases where granting
such an application will not adversely affect life and property in the air.
(c) Frequencies listed in the introductory paragraph of this section are
available to control towers and RCOs for communications with ground vehicles
and aircraft on the ground. The antenna heights shall be restricted to the
minimum necessary to achieve the required coverage. Channel spacing is 25
kHz.
