Yes, we are using their antenna, and you are correct that we do have massive gaps, currently. Because of the expense of the APs, we have not been deploying them in 360 degree fashion. We do a lot of 900 MHz and have been installing them where we need additional capacity. So if we have a loaded 900AP (these are already sectorized as that is the first step we take in adding capacity), we'll take a 320 AP sector and face it in the same direction as the loaded 900AP, and then convert customers onto it. Currently, 3 is the maximum number of APs we have on a single tower. Also, none of our APs are currently GPS-synced, but we our installations seem to be far enough apart and/or with enough downtilt, and we have been paying close attention to our frequency selections, that it hasn't been an issue. I've been waiting for Last Mile Gear's CTM-2 or was thinking about buying PacketFlux SyncInjectors, pending Forrest's comments.
