Be interesting to see what kind of channels will be available if I build this 
network.  Got something 11 paths.

Max channel bandwidth is 56mhz, but you should easily be able to get 250Mbps 
out of a 40mhz channel... I'm not sure there's much point in going in narrower 
than that. Actually, doing SISO at a 56mhz channel might make more sense, that 
should get around 275mbps at 256qam (and a bit more if the link will do 
1024qam, obviously), but then you'd only need a one polarity, so it may save a 
bit on coordination, and you wouldn't need to buy the extra duplexers.

  What is a common channel BW?  40 MHz?  I suppose it depends on congestion.  I 
only need about 250 Mbps so lower order modulation may be desirable and perhaps 
narrower channels too.

  Of course, the exact configuration is based on your license and which 
frequencies it is supposed to operate on.  The above configuration is just an 
example.

    They are like that, but 3x bigger.  On top, the lid comes off and the 
duplexers go beneath the cover.  If your link is 'High' then you will want 
'High' duplexers for both sides of the link (x4 total - two extra to purchase) 
- they will go in a configuration like 1-3-3-1 on one side and 3-1-1-3 on the 
other side.

      They come with 1 duplexer (setup for SISO) - you need to buy the second 
one separately to do MIMO. You do need to figure out what frequencies you're 
going to be using before you buy the radios, since there are two different 
duplexers, depending on which half of the band you're in.

      You need one frequency pair on both polarities (for MIMO).

        Do they all come with two N connectors or do you have to pay more for 
duplexers?  Not quite sure how to buy or license.  I guess you have to have two 
pairs of frequencies?  Or at the very least, both polarizations on the same 
frequency?

        Trying to collect some budgetary estimates on what my project is going 
to cost.
