RG-400 High-Isolation Double-Shield 50-ohm Coaxial Cable

RG-400 is a high-isolation 50-ohm coaxial cable that is ideal for critical, very low signal level, low noise applications as well as high power handling for RF equipment interconnections. Proper terminations on RG-400 cable assemblies provides extremely low crosstalk and very low noise ingress with a double-braid shielding effectiveness that results in over 100dB of isolation across HF frequencies. This cable is Mil-Spec equivalent to M17/128-RG400.

RG-400 is compatible with N-type and PL-259 solder type connectors with UG-175S reducers for RG-58 size cables.

NOTE: RG-400 has an OD of 0.195 inch and is NOT the same as DXE-400MAX which is 0.405 inch OD.
