Coaxial Directional Couplers for UHF-VHF Features * Low VSWR Broad Frequency Range High Directivity * Broad Coupling Range Field Replaceable * Compact Design Light Weight e Any Coax Line Size CD Series Coaxial Directional Couplers These loop couplers are designed, manufactured, and laboratory compensated for any coupling value between -30 dB and -60 dB for any channel in the VHF-FM-UHF bands. The highly directive coupling loops provide high accuracy in forward and/or reflected power measurements necessary for determining VSWR on the line or other operations.
