Isn't the localizer antenna down at the other end of the runway? If a pilot
is departing from the end, the localizer signal should be 700 feet wide at
that point.

It may be the localizer that you are interfering with, not only the GS.

Well, if it's only a problem when an aircraft is on the ILS and it's

I'm not sure that's the only time it's a problem. It just the minimum
that the tower is required to keep the area clear. I would expect that
ILS can be interfered with regardless of the current weather.


I think the idea is that even a distorted GS will be accurate enough to
get you to within 800/2 of the runway.
