The range of a locator beacon is much shorter than that of an NDB because
  • A
    locator beacons have a lower power output.
  • B
    locator beacons have no sky wave.
  • C
    locator beacons are always situated near airports.
  • D
    locator beacons have a higher frequency.

The range of an Non Directional Beacon (NDB) depends on several factors. It depends on output power, antenna, ground conductivity, frequency, site conditions, latitude and the condition of the ADF receiver.

Typically NDB’s have a power output ranging from 25 to 125 Watts that serves a reception of approximately 100 NM.

An emergency locator beacon is a radio beacon used to locate airplanes that suffered from an accident. The minimum power output a locator beacon needs to have is 50 mW. Typically the locator beacons have a power output of 5 Watts.
