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.


They're at opposite ends of the runway and you're not going to interfere
with both of them simultaneously, but your taxi route may take you through
both of them.

How many fields are there where this is a concern? I would expect most
fields with the congestion to require marked ILS critical areas to have
full-time towers.
