LMR240

This is a coaxial cable with foam insulation. It has a good attenuation and shielding effectiveness.It 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 4D-FB coaxial cable;
• RoHS compliant;
