This was a hot tower.

So was this Tower hot? Or just had radials on it?

Not that I recall.
This picture is from when the tower was no longer hot, but our cables
are still there. You can see the heliax coming down the right hand
side on the insulated standoffs. Our cat5 was attached to that and
then drooped into the shack with the coax. The bundle of cables on
the left are new cables now that the tower is not hot. The AM
Feed/tower lights are in the solid rod at the bottom of the tower.
This was a 1/4 wave stub tower, so at ~100 feet the insulated
standoffs stopped and everything was just attached to the tower legs
from there up.

You didn’t have to isolate your cat5 when it left the Tower into the
shack?

Years ago we were on a hot AM tower until the station removed the
AM Transmitter. I don't remember having to do anything special
with our cables coming down the tower, other than they were
insulated from the tower itself. In our case there was a large
Coax running up to an FM Antenna that was on insulated standoffs,
we attached our cables to that, and just followed the coax into the
shack.
We did pay to have the tower checked for tuning before we hung our
equipment. Good thing, the tower was out of whack before we
started, so they couldn't blame it on us.

Probably iso coupler

You thread the cable through the copper tubes that are part of
the load coil network.
The DC/AC choke circuits are made to power the tower light
circuits. Not sure who makes them. Have seen them at all the AM
stations.

Explaining snaking?
Who makes a DC isolation unit?

Standard isolation unit. You can also snake the DC through their
feed inductor.

Let’s not get into the weeds of putting stuff on an AM Tower.
If I’m crazy enough to try it....
What’s the best way to isolate DC coming from the shed to the
Tower?
Every thing else will be Tower mounted and bonded to the Tower.
