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. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com -------------------------------------------------- From: "Eric Rogers" <[email protected]> Sent: Saturday, October 31, 2009 8:30 AM To: "WISPA General List" <[email protected]> Subject: [WISPA] Backhaul Questions > Ok guys...Looking for both Mikrotik experience and others.
