I suspect it has to do with the location of the antenna. I don't =

The glideslopes are as they are all positioned to bring you to the =

By far the most impressive localizer antenna I've ever seen
is on the top of Aspen Mountain, aimed out across the Pitkin County =
Airport
and the valley beyond to the northwest.
It's an array of, I think, sixteen rugged Yagis over an expanded-metal =
screen.
However, I doubt that localizer course width at any threshold was a =
factor
in the design of this particular installation. It's for missed =
approaches only.
