I started hearing more and more thunder to the south (from home about 15
miles away). Alarms started going nuts. Whole tower down? WTF! Sure
enough, looking at the radar showed an orange/red-ish blob over the site.
I want to say I've seen this before. It was raining for 4-5 hours
straight so the ground was very saturated. Like a pond saturated.
Perhaps that acts as some kind of barrier and the lightning seeks
structures and utility poles more often. All I know is when we get good
rains in the spring and the soil is fairly wet throughout the summer, we
have a lot less damage to gear on towers. Very dry and very wet soil
seems to be bad. Maybe some dielectric effect. Those are my theories anyway.

This lightning storm was an oddly destructive one. I had what appeared
to be a fried PoE injector at a customer's house - the power supply
and RB260GS were both OK, but the customer's router had a fried WAN
port as well (fiber customer). I'm going to do some testing on the
PoE injector to see if that was the problem - it did smell a bit burnt
though.

GIGE-APC on the Mimosa. I don't have anything SS wise up-top.
I'm a bit torn on whether or not that does any good, plus
manufacturers don't like recommending anything.

The surge suppressors we have at that site are
L-com/Hyperlinks. A couple were blown top and bottom. Another
radio was only the top and another only the bottom. The 900 AP
board wasn't burned up, but dead. Lost that port on the
MikroTik. Both SS's on that were dead. I'm going to rebuild
everything at that site and use GIGE-APCs at least at the bottom.
What SS did you have on the Mimosa?

Yeah, I had a Ubiquiti Rocket and some nanobridges on the
same tower, albeit lower, that didn't skip a beat. I go to
all of the trouble of running dedicated power and optical,
only to have some cheap Ubiquiti stuff outlive it - makes you
wonder. The surge on the Mimosa went through the SS and
knocked out a port on my CCR - guess that will have to be
replaced as well.

Had a 5.7 Cyclone omni and a Antel 900 omni. So we flew
the Phantom up first to see if those antennas were
vaporized. Surprisingly they were still there. The
Cyclone still worked, but the timing port was dead. Power
port timing died on it last year. 450 sectors, AF24 and a
Force200 were perfectly fine. Some stuff and not others,
I don't get it. It killed the inverter in the APC UPS. No
doubt it came in on the utility after discovering that.
And then all of the tripped breakers after that. Yeah,
that'll be the next tower to get a DC UPS. And a whole
panel surge suppressor.

I lost a SIAE radio as well as a Mimosa A5 - both
were properly grounded, the SIAE was optical with
dedicated power wires as well. Also had a couple
customer's routers get fried. Overall, not a fun
day. I would rather be at Lake Shelbyville...
