Coaxial cable carries the signal from Xfinity/Comcast to each modem. Comcast has a cable network running through the tunnels underneath the buildings, which branches off into individual coaxial lines that run up through the walls and mechanical rooms to the modems for each living area. Coaxial cable consists of two "wires": an inner conductor and an outer sheath that serves as the ground wire:
CadetNet uses primarily RG-6 coaxial cable terminated with crimp-on F-Type connectors. All tools necessary to crimp coaxial cables (in addition to raw RG-6 cable and F-type connectors) are available upon request from CadetNet, and below is a quick instructional video on crimping coaxial cable:
Coaxial cable has a maximum cable length of around 3,200 feet, meaning that it can stretch much farther than ethernet cable without issues.
While no ongoing maintenance should be required relating to coaxial cable, occasionally the end connectors come loose and cause the connection with the modem to fail. If this is the case, simply remove the end connector, fold back the braided outer layer of wire, and re-crimp the cable with a fresh F-Type connector. This should resolve most connectivity issues stemming from broken coaxial cables.
