CONT

The localizer signal emitted from the transmitter site at the far end of the runway is confined within an angular width between 3° and 6°. The localizer provides course guidance throughout the descent path to the runway threshold from a distance of 18 NM [nautical miles] from the antenna between a height of 1000 ft above the highest terrain along the approach path and 4500 ft above the elevation of the antenna site.

CONT

In a similar manner as the LOC signal, the GS [glide slope] sends a UHF [ultra high frequency] carrier signal with the same two 90-Hz and 150-Hz sideband frequencies that aircraft instruments determine as above or below the desired glide path. This is approximately 3 degrees to the horizon which gives the aircraft a descent rate of approximately 500 feet per minute.

OBS

LOC: localizer.
