VOR RECEIVER: In many modern aircraft one control unit is used for both the VOR receiver and the VHF communications transceiver. When located together, the radio is called a NAVCOM (See Navcom Control Panels figure, on the right). The VOR signals are received on the antenna, normally located on the vertical stabilizer or on top of the fuselage. This antenna resembles a "V" lying in a horizontal plane. The VOR receiver converts signals from the antenna to the readings displayed on the navigation indicator.
