USMCflyer:

This diagram shows the multiple glideslopes that are normally generated. I also found technical discussions that said “false courses” are also normally generated by the localizer. As I remember from USAF instrument courses, these false courses are attenuated by shielding the transmitter antenna to favor propagation only towards the service volume. As mentioned earlier, snow drifts can bend these signals by reflection.

I thought the Air Force Instrument Manual at one time showed these multiple “localizer beams.” I thought they were at predictable angles/degrees from the main beam, just like the false glideslopes.

Do I have that right?
