KFI

Is their antenna rebuilt? Google Maps & Google Earth show a nice, new-looking
stick, but there's no indication of when those pictures were taken.

Sorry to have a limited vocabulary, but what's an STA?

The FAA ruled that they could not rebuild at 770 feet, but at about 120 feet
shorter, which would not meet a class A radiation minimum. KFI is appealing.

It's a special temporary authority (or authorization) to operate with
facilities at variance form the licensed values.

If they lose, do you suppose they'd build at the lower height or find another
site?

Can they increase radiation toward land if they go directional away
from the open sea?

I think KNX studied this, since their site in Torrance is farther from the
center of the metro area. They especially wanted a better signal in the inland
empire. But a directional signal east would not reach San Diego (nation's
seventh-largest city) or parts of the state north and west of LA.

KBIG does a good job from their site on Catalina, but I don't know how, since
it's a rock, and their stick is on a mountaintop there. But they only operate
during daylight, and probably don't reach the inland empire very well.

KFI's site is perfect for the greater LA area. KNBR does OK with a Franklin
antenna at about 450 feet, I think. They'd do better with a half-wave though,
but it's an airport issue there too.

I'm surprised KFI is having the problem. If the FAA decided that the 750 feet
stick presented a safety hazard, why didn't they try to get the station to take
it down (or did they?). Since the station already had the tower (which I think
predated the airport), their lawyers would seem to have a good argument that
they can rebuild it.

KGO does really well with 1/4 wave antennas. KTAR in Phoenix as well.

They would probably build and use some type of top loading to get the
minimum efficiency y for licensing. Getting a tower built in metro LA today
is nearly impossible.

There is no place they could get a multi tower site licensed with the
minimum height required for a A 1 clear. They would more likely stay where
they are and use a smaller tower.
