7D-FB

This is a JIS foam coaxial cable with solid inner conductor. It has a good attenuation and shielding effectiveness, and has been widely applied to radio transmission,base radio antenna station and other communication systems.

·        50 Ohm data signal transmission;

·        The shielding layer composed of aluminum foil and braiding has a good shielding effectiveness;

·        Excellent performance in high frequency,VSWR stability;

·        Similar to the LMR400 coaxial cable;

·        RoHS compliant;
