It is in good condition and is not punctured or cracked BUT the paint has flaked off in several places (see images). This one was removed from G-VFAB during tear down and has been in storage since. This is a ILS Localizer antenna used on various types of aircraft. If you have a cone or mast mounted in the middle of the VOR/DVOR station, that is normally a sign of a collocated DME. Sensor Systems Aircraft ILS Localizer Antenna S65-147-7 Used. The rotating signal generating the phase difference is used in the older conventional VORs. If you see around 48 little antennas arranged in a circle of 44' diameter, that would be a doppler VOR station which uses a doppler shift between the AM reference signal to the FM variable signal to generate the phase difference. Quoting tdscanuck ( Reply 1): VOR is transmitting to signals.a main signal (the big central antenna) and an electronically rotating signal (all the little ones). The more modern the installation, generally the more antennas you will see installed for a given function. Quoting RJSampson ( Thread starter): Why does a localizer station have multiple antennae and, for that matter, why does a VOR have several (or much more than several) transmitting antennae?Įssentially it has to do with antenna design, with better mathematical models of how antenna radiate their signals, more advanced antenna designs are used to provide a more uniform and accurate radiated signal and that is less susceptible to the normal inherent errors in those systems, and the physical surroundings. These documents is more than you will ever need to know operationally as a pilot, they describe how the various systems work.

The localizer is normally seen at the end of the runway, aligned with the runway center line. Quoting RJSampson ( Thread starter): However, the mechanics of a localizer (and for that matter a VOR) station were never discussed. Telluride (KTEX) in Colorado, USA: Source As visible, the localizer antenna for RWY 09 is located where the glideslope antenna is usually found, abeam the touch down zone.
