This cable family of "Low Loss Cable" is distinguished by double shielding and lower attenuation or cable capacitance of the standard cable (e.g. RG58).
Application: medicine, maximum frequency, military, Antennas and EMC
RG223: (Sheath colour: black) 50 Ω, RoHS-compliant;
Temperature range -25°C to +85°C
Alternative: RG223 U with inner conductor wire
The RG223 is a 5.40 mm strong radio frequency cable. Double shielded and suitable for most RF applications.
