That looks like the whole tower is standing on insulators.  I'm not so sure the ring transformer is for lightning protection (although the spark gap bypassing it will do so)
Yes its for an insulated antenna, but does both jobs. Isolates the 110 from the tower and act as a lightning gap.

Just noticed that a mod changed my signature. How long ago was that?

Yeah, isolation transformer with a spark gap.

The thought occurred, but most wall warts are made for indoor use.

Still, definitely spiffy.

I must be getting dyslexic. Every time I see this thread title
I read it as meat bacon.
If ye love wealth better than liberty, the tranquility of servitude better than the animating contest of freedom, go home from us in peace. We ask not your counsels or your arms. Crouch down and lick the hands which feed you. May your chains set lightly upon you, and may posterity forget that you were our countrymen.

I shifted gears on the whole thing.

The red strobe beacon draws a whopping 70 milliamps, or less than 1 watt at 12 volts.

I now have a 5 watt 12 volt solar panel, a small 230 Amp/Hour garden tractor battery, and one of these:

No attachment to the household 115vac wiring at all.   =D

Very cool, so if you take a direct hit, you just replace the lighting system instead of calling the fire department to put out the house fire. :)

Glad we could help !!!!

 =D =D =D
Some days even my lucky rocketship underpants won't help.


Bring me my Broadsword and a clear understanding.
Get up to the roundhouse on the cliff-top standing.
Take women and children and bed them down.
Bless with a hard heart those that stand with me.
Bless the women and children who firm our hands.
Put our backs to the north wind.
Hold fast by the river.
Sweet memories to drive us on,
for the motherland.

Actually, you guys helped quite a bit. 

We suffered a lightning strike to a tree earlier this spring, just feet from the deck where this weather station will go.

It blew a strip of bark completely over the house and onto the front sidewalk, a good 25 yards away from the tree.

We were sitting in the dining room on the other side of the patio doors from the deck and tree when it hit.  To say a fresh change of underwear was required is an understatement.

Roberta X even drew me up a schematic showing multiple MOVs, gas discharge tube devices, and induction coils in the circuit to create a layered, sacrificial defense.

Her biggest caveat, which sunk in to me, was that if the mast took a "once in a blue moon" hit, none of those things would prevent my household wiring from getting zorched.

I don't need to set my house on fire for the sake of a pretty red beacon on my weather station.
