Notes
A Stoop links to the nearest hub, and to one or two neighboring Stoops where it can see them, so that a single failed hub rarely takes a house offline. Hosts provide the roof and the power; the network provides everything else.
Connectors are sealed with the specified silicone sealant and self-amalgamating tape. Use only the specified sealant; it is safe when used as directed.

Revision history
Lower power draw, a better thermal path for summer roofs and a gland that seals around damaged cable jackets. Fully backward-compatible with R4 and R5 mounts.
Redesigned around parts that stayed in stock through the shortages. Added a status light visible from the street, so stewards can check a node without a ladder.
Moved to 802.11ac. New enclosure with a hinged lid, so a radio can be swapped on the roof without removing the mount.
Moved to 802.11n 2×2. Added a surge arrestor and a proper ground lug after a lightning season in Paterson.
First purpose-built design: a single-board router and a commercial panel antenna in a sealed enclosure. Passive PoE replaced the separate power brick on the roof.
Secondhand consumer routers, reflashed, with salvaged external antennas in plastic food-storage boxes. Eight were built for the first network in Bridgeside, alongside the relay under the bridge.
