Their products look very good
Another vote for Oberon products. This is the one you would need:
This is listed for AP340/AP350, so I'm not completely sure an AP390 will fit. But I think it would; the antennae orientation may be the one issue. You would need to check with them first.
We've tested them, and they are very sturdy. They'll easily withstand lacrosse balls being winged at them.
