A ground to air crossband repeater allows FM ground radios to communicate with AM aircraft radios. Fixed locations, such as a control tower or FM stations, can be provided with extended coverage to aircraft that are using AM radio equipment.

Ground to Air Crossband Repeater

A FM ground station or control tower would signal an aircraft through a FM link to a remote radio repeater. This signal would be crossbanded to an AM radio which would allow a greater coverage area. The aircraft would communicate through an AM signal to the repeater station which would be crossbanded to a FM radio that would communicate back to the control tower.
