Excerpt From https://apps.fcc.gov/edocs_public/attachmatch/FCC-02-139A1.p...
Under the revised rules, MURS units are: • Permitted to have detachable antennas; • Permitted to have external antennas up to 6.1 meters (20 feet) above a structure or 18.3 meters (60 feet) above the ground, whichever is higher; • Permitted to have a total power output (TPO) of up to two (2) watts (instead of two (2) watts effective radiated power); • Not permitted to be used as cordless telephones, radiofacsimile (imaging), or for continuous carrier mode operations; and • Not permitted to be used for repeater operations
Without a repeater, I would assume it is very difficult to imagine a hop-by-hop network?
