I posted this a few months back and got a few "too bad we just threw away a bunch of gear" answers so I'm trying again as a reminder. I'm thinking of posting this every 3 months if no one considers it annoying.
I'm with a group of hams using wifi gear (mostly Ubnt/MT) at 2.3ghz in a project to modernize amateur radio communications. We don't have a big budget so if anyone has ~2.4ghz Vpol 60-120deg sectors, higher-gain antennas or Ubnt/MT/other wifi CPEs available cheap/free, please let me know and we can look at shipping. Or if any one here is a ham and has the free time to start building additional networks (I know that's unlikely) I can answer questions/help.
