I don't know, but I agree. Next to no rain in June, then July and BAM!

Subject: Re: [AFMUG] Who cares if the network is down
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...
