LMR195 description:
LMR series cable was originally introduced by the United States, covering the DC-6G, low-loss, high-power, flexible good RF coaxial cable, and for indoor and outdoor use of the cable itself has additional environmental protection measures are widely used in 3G communication base station, RFID systems, satellite communications systems, military communications, and some that require low-cost radar.
Superior production of low-loss 50 ohm coaxial cable performance super soft LMR series, surpassing foreign brands, great price advantage shelf.
