It looks like something that should be an industry standard fitting. It hardly makes sense for Netgear to come up with its own unique design for something like this. Then again, not everything that Netgear does makes sense.
Much as I enjoy ragging on Netgear, it seems to me that every "outdoor" WiFi device I have seen is wildly different in appearance. A key part of Netgear's design was the "locking mechanism" to keep people from simply walking off with a $300 item. "Industry standard" seems like asking a bit much.
If Netgear did make parts like this available for purchase, my guess is that people would HOWL at the cost and never buy any.
