As I said above, I'm not buying any more of them. Single polarity.
So far I've not had any issues aside from the water problem. The
grids, brackets, etc, all still look almost as good as the day we
installed them.

Do not get the wire grids, they rust terribly after a few years.
Get the diecast grids, same feed, no rust. L-Com sells them.
Actually, don’t use grids period, single pol is a thing of the past.

Laird Technologies GD58-29 and GD58-26, formerly PacWireless.
Good antennas, signal usually worked out right on target.

Which models of grids are those? We don't use the cheaper
professionally but I have some old ones I was going to use for
my amateur radio wifi project.

These had already been in the air for years, most were
purchased back in 2008. Started failing around 2012. Shame
too, they were excellent antennas. Same model is still on
the market. I'd buy more but they're single polarity.

What would cause an antenna to fail after 4 years,
other than target practice or falling ice? Hose off
the bird poop and they should be good as new.

Looks nice. I'm a bit scared to check on the price though.
I definitely see the point about the connectorized
antennas, though I've had issues with antennas going
out before the radios. They did last 4+ years though,
so no real complaints there.

I just don't like putting anything without
connectorized antennas on towers anymore... it
makes things much easier to upgrade later on if
you can leave the dish alone and just swap radios,
and force 110's are cheap.
We still use plenty of NanoBeams and NanoBridges
for customers.
NanoBeam M5's do work very well for PtP links, as
long as you can use 5.8ghz, but NanoBridges often
don't seem to perform as well as they should.

It will also change a bit depending on
what channel width you're using... 10mhz
will gain you a few db over 20mhz, etc.
I'll generally go to a larger antenna on
anything over 5-6 miles these days...
actually I won't use NanoBridges for PtP
links at all anymore, but that's another
story.

You did account for the fact that
Ubnt antenna gain specs usually
add an extra 2-3db "in taxes" right?.

Thanks.
Accounting for 3dB "gain" added
for MIMO and 18dBm tx power at
full modulation makes the math
work out for what I'm actually seeing.
Problem is I'm still only at MCS
12, which should be 22dBm tx.
I think they add 3dB to every
number on their datasheets
accounting for MIMO, which doesn't
work out quite as nicely when
doing the math.

Make sure you account for Tx
power at full modulation vs.
lowest modulation. Always
calculate based on full
modulation.

I thought so as well. Could be
he's talking about the gain
being +3dB on the data sheets
assuming for the gain due to MIMO.
At 12 miles I get a -71. The
math shows -61.
Most of my NBM5 links are
similar. I get much better
signal with my old 802.11a +
PacWireless grids, usually
right on the math.

Well you're losing 3db
because of MIMO. At least
1db from what the antennas
say. What's the signal now?

I've got a few links

According to the math
I should get a decent

according to that same

have higher signal in
every single link I've
done.
My question here is
what is the longest
link you've done with
the NBM5 25 and what
is the actual gain on
these units since they
don't seem to actually
gain 25 as they're
suppose to.
I'm not opposed to
using a Rocket and
larger dish, just
trying to see what the
actual limits to the
device are and what
the actual gain is for
math.
Currently I've got the
24 mile shot with a 29
and 26dBi grids,
decent, but still
using 2008 MT
hardware. I need more
speed for growth.
