Aircraft Antennas for ILS
0 commentsThe localizer system works in the same frequency range as VOR, therefore the two systems can, and often do, share the same antenna. This is the horizontally mounted "V" shaped antenna you will see atop the fuselage, or vertical stabilizer. The localizer antenna should be installed along the aircraft's centreline.
The glidescope antenna (pictured) is also a horizontally polarized antenna, but is considerably smaller than the localizer, due to the higher frequency of operation. The ideal location is in the nose/radome area, where the antenna can clearly "see" the transmitter during final approach.
The marker beacon antenna should always be mounted on the belly of the aircraft, for greatest effectiveness.
