Who's using these?
What's inside the "Simper"?

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.

NBM5 for a lot of tower to tower shots.

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.

I'm thinking they may do the same with the tx power as well.

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.

I thought you gained 2db because of MIMO?

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 out there with the
NBM5, longest is around 12 miles.
According to the math I should get a
decent shot at 24 miles, but according to
that same math the NBM5 should 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.
