[HamWAN PSDR] mantbox19s certification?

The AC radios in general seem to have hit or miss support for the narrower channel widths we use for sectors (5 / 10MHz). We’ve had reports in very rare instances of AC radios working. In general they don’t support the narrow channels and we don’t recommend them. Looking at the product code, "RB921GS-5HPacD-19S” it looks like it may be a sector antenna with a built in NetMetal 921. We use NetMetal 921 models for backhaul links, but they don’t support the narrow channels, so another point in a “probably not” sort of guess.

We have in one case experimented with an air fiber at 3GHz on a backhaul link and it works fine. I also believe the Tampa Bay folks use some 3GHz backhaul links. In terms of setting up your own network, you’re welcome to set up the backhaul in whatever means makes most sense to you. The standard covers the stuff that is user facing, so that a user can take their gear to another HamWAN compatible network and it should work without reconfiguration. In our case, it’s worked out fairly conveniently to use part 15 5ghz space for most of our backhaul.
