Hi All,
After seeing the comment about 100mhz of unlicensed in the TVBD RO I
decided to ask some questions. I thought you guys might enjoy this
exchange.
It's a bummer that John's going to retire. He wrote much of the part 15
rules that we operate under and has been a source of many answers
Perhaps John wants a job working part time for WISPA?

see Antenna Requirements on page 101. Fixed device transmit antenna
limited to MAX 30 meters high, also the receive antenna must be MIN 10
meter high.

That is a grey area. Not all 15 dBi yagis are created equal. They all have

And S11 can cause a load pull of a transmitter causing different out of

That is why you will see a list of approved antennas. Including yagis.
However there is the part

Wind generators are good if you have plenty of wind and no ice.
Our problem has been that we need their power during the worst weather.
And that is when they fail. They wear out or get loaded with ice and tear
apart.

Your panel sizing is right on, but you don't need that much battery cost.
Golf Cart batteries, which are near 200 each, are more than enough for a 12
volt system.

Lead acid batteries won't freeze unless discharged more than 50%.
for winter, just insulate them well to shield them from severe temperature
spikes and make sure you have more charging power than you need, and you're
good to go.

I have used a AIR-X for 4 years now. The blades are a composite plastic
and the ice WILL NOT stick to them. I've been there when the pole
supporting the generator had nearly an inch of ice on it and the antennas
were all coated too thick to break off, and the genset blades were ice free.
You're special, Chuck. :-p

Not our building, but ours looked just like it. This is after a week of no
possible way to access the site. And of course no sunlight for a week of storm.
Then with panels being coated like this, no sunlight until you get up there to
chop off the ice or do other things that are more effective.

Thanks so much for the insight and great information. You just saved me
having to make all those mistakes all over again. I was definitely
undersizing the system and I'd bet most folks would tend to do that, trying

One more question: I read that solar panels will still output on
We can even detect a little charge due to moonlight.
Clouds are such variable density it is hard to give a meaningful answer.
Plus there are days that are scattered, broken and overcast cloud
conditions.
We typically see a 50% reduction of current when clouds pass over on the
telemetry.

Also the assumption that the TVWS rules are the same as the rules in
the other bands is also a far, far stretch. The TVWS rules are clearly
not same as the rules in the other bands, not by a long shot.

We put together a wiki entry for our customers that explains the entire
process of 3.65GHz licensing, from applying for an FRN number, to
obtaining a nationwide license, to registering each site location.
Maybe this will help some of you guys too:
Using StarOS, we have tested them with 3.5GHz antennas. They got what we
would expect them to get with respect to SNR, with a slight loss due to the
3.5GHz antennas.
Two issues...

new version XR3 - 3.7 which had
I really can't remember about throughput. This was really what the board

what exactly is the battery technology and brand you suggest? if I have a 5

The process of getting the license was easy. The site registration was
completely new to me and took quite some time. The FCC has a whole batch
of terminology you may know nothing about.

And can come back from 100% discharge at -40 to be fully charged.
