I agree for 6 meters and down that RG8-X would be very suitable, that RF loss is minimal for a 100 foot run, and that the hose reel is the best carry method.
However, for emergency communications where improvised antenna setups may need coax to be dropped off building roofs, run through office windows, doors and down access stairs and hallways where it may be pinched or stepped on, you need a more durable cable as assurance against failure.
Our RACES unit was extremely fortunate several years ago to receive a donation of several thousand feet of military specification RG-214, from a public utility which no longer needed it to service a no longer used low-band VHF system. This cable is double-shielded cable with solid poly dielectric and noncontaminating Type II direct bury jacket, and is extremely durable. While bulkier than RG-8X, 100 feet still carry easily on a hose reel. It has proven its worth several times over in hurricanes, floods and other field deployments since 1999.
