Comet CK-3NMO - Cable Assembly, NMO Base, 16.9 ft. Cable Length, Includes 18 in. RG-174 Pass Through Cable, PL-259. Comet CK-3NMO Deluxe Mobile Mount Cable Assemblies are designed for use in a 3/4 in. hole or with the RS-720NMO lip mount. These CK-3NMO assemblies feature approximately 16.75 ft. (5 m) of coax cable, of which the first 18 in. is RG-174 Type for easy entry through your vehicle's weather seal. The 15.25 ft. of remaining cable after the RG-174 is low-loss mobile cable. They also feature a Teflon insulator and a 24K gold-plated PL-259 center pin. These assemblies also include a detachable barrel for ease of routing, if needed. A note about Comet coax: The mini coax is neither RG-188 nor RG-174… it is actually 1.5D-QEFV Japanese coax. Comet states it is 'RG-174 type' coax because they have similar loss and diameter specifications. Initially RG-188 was used in comparison but was changed to the RG-174 comparison because they are more similar. The balance of the coax is Japanese 3.5D-QEFV. There is no 'RG' equivalent to 3.5D-QEFV. RG-58 connectors will not fit the 3.5D-QEFV coax, the Comet coax has a larger outside diameter and a larger central core and has about 30 percent less loss than RG-58. All of the coax cables produced by Comet use the Comet (Japanese) low loss coax. Max power for Comet CK-3NMO coax cable assemblies: * 25 MHz: 200 W * 140 MHz: 70 W * 440 MHz: 45 W These power ratings are due to the use of mini coax to allow convenient installation.
