Bridgewave (REMEC/Mosely) and others make much more expensive, carrier grade, fiber-connected 60 GHz PTP equipment that is good for five nines reliability at 500 to 650 meters in a Seattle-like rain zone. Somewhat less distance in places that have higher mm/hour rain rates. These are serious products that take direct 48VDC power, singlemode fiber connections, and have dedicated management interfaces. "serious" 60 GHz equipment is built to the same standards as $15,000 80 GHz links and is used by a lot of large ISPs. Most of whom don't consider themselves to be WISPs, but rather ISPs that happen to use PTP millimeter wave when it is necessary or justified. I have not personally seen a Metrolinq 60 GHz but I have seen photos of one disassembled, and it is literally a USB 802.11ad 60 GHz dongle hot glued to a plastic thing in front of a reflector. Scary.

It generally holds up during torrential down pours. Random fog events will cause it to become trashed. The link is .6 miles. I expected it to fade from time to time. The problem for me is the fail over does not happen properly. It's a gosh darn USB dongle attached to a reflector dish. Don't expect too much out of it.

We lose our IN link every time it rains. And the 5GHz does not fail over seemleasly at all. There is packet loss and high pings until the 60GHz finally dies. Then it sometimes flips.
