Default Status PowerFLARM USA

"US PowerFLARM ‘A’ and ‘B’ port do NOT have the same connector due to
an unfortunate FCC requirement. If you screw in incorrect antennas
(with incorrect SMA sex), *you *will* damage your PowerFLARM."

What is the nature of this damage? The conector is damaged or the
elecronics?

The SMA connectors that will be damaged -- essentially screwing together an outer male/female pair but with both connectors having internal male center pins. The inner pins will either bend/break or spear into the teflon insulator of the other connector and break off there, never pretty. These things should never be hard to tighten up using fingers only, so if they seem anything more than that stop and look. And before connecting make sure that the SMA connector inner pins are always opposite gender. Reverse SMA connectors are a stupid pain in the ass....

Required by USA FCC - USA only - total idiocy.
PowerFLARM in other countries do not have this issue.
