Notes
Relays are the least visible part of a network and the most important to keep aligned. Stewards check every relay path after a storm, and re-aim any link whose signal has dropped by more than 3 dB.
In service

Revision history
Automatic fallback to 5 GHz when heavy rain fades the 60 GHz link, so rain slows a link instead of breaking it.
Moved to 24 GHz and 60 GHz. Rural variant with a guyed mast kit, first used for the ridge links in Tug Fork Hollow.
Commercial 5 GHz point-to-point radios with a proper alignment procedure and a written path survey for every link.
Two salvaged satellite dishes with 5 GHz feeds, pointed by hand. The first one was mounted under the bridge in Bridgeside and is still in service, though not much of the original remains.
