Additional information
*All frequency and attenuation values are based on a 10 meter cable assembly test including 2 bulkhead connectors (75 ohm).
BNC connector for RG179 coax leads use Amphenol 112133 or equivalent.
BNC connector for Mini-RG59 coax cable use Belden 1855ABHD3 or equivalent.
SubConn® Coax connectors are dry mate only, and cannot take open face pressure.
Locking sleeves are required. No greasing in the actual coax part.
Minimum bending radius on inline cable is 100 mm.
Recommended SMB termination for Coax, see SubConn - Technical information.
