cable with a PTFE
jacket. The double shielded
construction of these cables gives outstanding
shielding effectiveness of greater than -85db at 18
GHz. The assemblies feature precision stainless
steel connectors designed to meet MIL-C-39012,
MIL-STD-348a or all applicable industry
specifications, and are available in straight male,
straight female, bulkhead, and right angle styles.
These cable assemblies feature low loss, excellent
VSWR, and are excellent to increase the
performance of any system.
