[PSDR] Spectrum allocation for point-to-multipoint sectorized cell sites published

Hello,

I've just published the proposed PtMP spectrum usage for HamWAN cell 
sites.  It can be seen at the Spectrum Allocation 
<https://www.hamwan.org/t/tiki-index.php?page=Spectrum+Allocation&structure=HamWAN> 
page.  Optimized for viewing @ 2560x1600.  :)  The point-to-point links 
between cell sites will not be allocated/planned before hand, and don't 
need to be published since no users will use those links.

Any objections/suggestions?

My biggest worry right now is when someone wants to use the ARC 34dBi 
dish to link to a sector, but the dish's frequency response may suck 
that high up.  The 21dBi grids seem to only lose 3dB of gain from their 
peak at the very top of the spectrum.  Not awful. Have not yet measured 
the 27dBi grids, but expect similar results.

One very important thing this plan does is identify the center working 
frequency for the sector antennas as being 5.855GHz.  That's the 
frequency at which radiation pattern measurements should be made, and is 
the very next task on my list.
