Depending on the airplane, many of the smaller ones pull the power on
down wind and just glide about the last half of down wind, then base and
final with the goal of setting down on the touch down zone. I carry
power all the way into the flare and have to adjust the altitude (above
ground) according to my distance from the runway. I typically turn
final about 500 AGL and put the gear down. With the gear up I have
about twice the glide ratio of a Cessna 172 at close to 20 to 1. With
the gear down it's more like a streamlined brick.

Been there, Done that<:-)) Unfortunately "when I had hair" I was a
skinny red headed kid with freckles who sunburned easy and now as an old
man, get to go to the dermatologist about three times a year because of
those sunburns.
"I believe" That he is in the "outer flight area" and not in a
transition area. "Typically" height limitations in these areas are 150
feet, but there are exceptions. Please note I said "I believe"! and
that there are exceptions.

We have a guyed (and lighted) cell tower just to the right of the glide
slope on the GPS 06 approach. It's around 300 feet tall IIRC, or about
twice my altitude at that point, but it's maybe 300 yards from the
protected area which is probably 300 feet wide at that point.
OTOH I was coming back into the airport after being gone for several
hours. I was on final for 36 which is our shortest runway. US-10
expressway runs across the South side of the airport and there was a new
subdivision just South of the expressway. I was doing one of these
gentle finals that passengers like, not the steep ones I like when
something just didn't seem right. Then I realized I was looking at a
tower ahead of me. A tower with a guy installing a TV antenna on top and
I was not as high as he was. I went full power, pulled up and rolled to
the right. The port wing passed over the guy on the tower and less than
10 feet above him. The left main was probably almost close enough for
him to check the tire pressure. (Remember I'm now in a rather steep
bank). Man but that had to have been noisy as at full power the prop
tips were supersonic and that big engine is not exactly quiet. The
mufflers are straight through and only about a foot long with 3" ID
exhaust stacks and each of those cylinders is about 80 cubic inches. I'd
bet it was a bit breezy too<:-)) The airport manager had difficulty
believing when I told him , but I understand the owner called the
airport quite upset until he found he was committing a federal crime.
The tower was gone right quick. Of course as soon as people moved into
the subdivision they started complaining about the noise and tried to
get the airport closed.
I love airplanes and flying, but no way would I build just a few hundred
yards off the end of a runway.
BTW if I had hit that tower I'd have ended up parking that plane in
somebody's house which would have ruined my insurance companies day as
well as mine and my now rich widow. 100 gallons of av gas makes quite
a show.
Commercial towers are treated differently than Amateur. You don't
really want to get into an area where the tower has to be lighted. You
can get quite close and still put the antenna 20 feet above the tops of
the trees as long as you do not line up with any of the runways. OTOH
if the tops are cut out of the trees you should probably seek a quieter
location.

If an individual they used to give you an answer right over the phone,
at least in the instances with which I'm familiar.
In this case I'd be more concerned about a national park or wild life
area. It does say "National Monument.
