-	The ILS service uses frequencies in the 108.1 MHz - 111.95 MHz VHF band (localizer) and a paired frequency in the 328.6 MHz - 335.4 MHz UHF band (glideslope or glide path). See the [[ILS]] page for more information.	+	The [[ILS]] service uses frequencies in the 108.1 MHz - 111.95 MHz VHF band (localizer - which provides horizontal guidance - that is - if the aircraft is to the right of the runway centerline, to the left of the runway centerline or right in the middle) and a paired frequency in the 328.6 MHz - 335.4 MHz UHF band (glideslope or glide path - which provides vertical guidance - if the aircraft is too high, too low or right "on the beam" or "on the glideslope" to come down to the foot of the runway). See the [[ILS]] page for more information.

	The VOR system also operates in the 108 MHz - 112 MHz band and the 112.05 MHz - 117.95 MHz band (50 kHz spacing in the 112.050 MHz - 117.950 MHz band).
