True. But the firing arc question assumes that PDUs are on smooth
spheres. But most planets are bumpy. Anywhere you put your PDU is
going to involve compromises and you will need secondary installations
to cover air corridors which may not have a good LOS to the PDU that
would be defending that sector. Furthermore, if you site it with LOS
being a primary concern, you get to build it on top of a mountain
(more expensive, more time-consuming) and then it is seperated from
the settlements. Perhaps enough to overcome the reluctance to just
slam it with a pair of tactical nukes launced from said fighters?

I'd shy away from putting PDUs in actual valuable territory. I mean,
what if you win the battle? Then your colony is trashed and it's your
own fault. Furthermore, major population centers are in places which
(typically) have good agricultural production and easy transportation
routes. River valleys are a favorite, which is not always the best
place to stick a PDU, LOS-wise.
Even when coastal fortresses were an effective defense, they weren't
necessarily located downtown, but typically at the entrance to the
harbor, or on an island just off from the harbor which could control
it with gunfire. A castle would (usually) be situated on a hilltop
near the town, not in middle of the market square.
Personally, my inclination for a planetary defense scheme runs like
Massive phased-array antennas scattered out all over the place for
Buried silos--SMRs--scattered randomly through the wilderness and
heavily camoflaged. They would have buried landline controls to
launch them, and the transmitters to control them after launch would
also be in the boonies and linked by hardline to the command center.
Which would be buried under a mountain.
Could also place batteries of beam weapons in places where they defend
good LZs, but that would be seriously secondary. Salvo Missles are
going to be better at shooting down stuff locked into an orbit.
Instead of a single big PDU, dozens of tiny installations scattered
all over the places, mostly in regions far, far away from anything
valuable. And since they are SMRs, after they launch, you can waste
time/ordnance shooting at empty silos. Doesn't hurt my feelings.
The population centers get PDSs. Lots of them, locally controlled but
linked into the central command facility.
But that would be secondary. I'd rather fight the fight in orbit
anyway. Less people live there.
