Specifications for "N" Connectors
_____________________________
N Series connectors are medium sized, and weatherproof. The coupling method utilizes a screw system designed for use at
frequencies up to microwave. These connectors are particularly useful where precision performance is necessary such as in
test equipment, satellite communications, MATV, computer LAN systems, and other high-tech electronic equipment.
Because of the quality manufacturing tolerances these connectors ensure excellent performance throughout 0-18GHz.
