Sounds like a case for using 3.65 for your BH links. Good engineering
around channel assignment and width and polarity would give you a lot of
combinations.

Eric,
I can only answer the non-MT questions :-)
For roughly $3,700 you could get a Radwin 2000 link, which is a quad-band
(2.4GHz, 5.2GHz, 5.4GHz, 5.8GHz) radio capable of 50Mbps each direction (or
100Mb aggregate). It does not support GPS sync, but instead supports HSS,
which allows all
I would try a 802.11N link. We are getting 55+ Mbit TCP through them
over distances of 28+ Miles.

Well, depending on what the radio was certified with, you could
theoretically go 40 miles in 5.4 GHz. I'm not sure I'd put those antennas
on a Rohn 25, though. :-p
MT 20 MHz can go 35 megs or so, depending on board HP and RF conditions.

How is that possible with a 30dB EIRP max limit? Sure you could use a
36dB dish but I can't see how you can turn the power down enough to stay
in compliance.
