Orthogon/Motorola 300 is 300 aggregate (and that's air rate - if you measure throughput w/ 1500mtu TCP packets, you're at about 260-280 Mb) And to get that speed - it requires the requisite SNR to support 256QAM modulation on BOTH HV within a 30 MHz channel -Charles

Hello list, I am planning the installation of a self-supporting tower for a startup WISP in Maryland. I am considering light duty off-the-shelf designs from Trylon such as the SuperTitan. I am trying to determine whether to include ice buildup as a factor in the tower purchase. I have obtained

Just visiting www.orthogonsystems.com to see if Spectra will do 2:1 Master:Slave asymmetric throughput like the Gemini (Spectra won't) .. I see the Gemini and Spectra have been rebranded as the PTP 400 and PTP 600, respectively. What stupid names! I hope to god they don't screw up the hardware as

I have looked at the AN Wireless product line and they look like great towers and are close by in PA, but they don't make anything over 120 feet. I need to get higher than that to ensure LOS to some key areas. I believe my ice question will be answered shortly, the county's communication site

Talk to the folks at AN, if you haven't.  I have found them to be very customer service oriented.  I would think they may be able to offer some suggestions.  I have one of their towers that I bought used from someone else and from the help I received, you would have thought I bought it new.

Trylon = solid angle iron. No hollow tubes. I like them myself. I have never tried the ANs discussed though. I am guessing it is a good tower if Johnny thinks so. Hey Johnny, did you lose a Trylon during the hurricane? Did you have an AN tower then also or is that what you replaced the Trylon
