 Typical Part #:                 WGSize-307 -Coupling(dB) -Flange1 -Flange2

The Model numbers listed above are the most common model numbers for W/G size, coupling and flanges however, these models can easily be altered to accommodate customer needs by following the Model # code system.  In addition the customer must choose the coupling value appropriate for application (30dB, 40dB, 50dB or 60dB) and insert it in the model number where dB is listed.

 

*For a dual unit modify the P/N by adding a D to the end of the basic model #, the direction of the coupling and the coupling value of the second coupling arm. 

Example P/N:  750-307-dB-C3-C3 becomes: 750-307D-dBF-dBR-C3-C3 when ordering a Dual-arm unit (where F=forward coupling and R=reverse coupling)

 Example P/N: 650-308-40-C3-C3 is:
WRD650 - 308 Coupler (Type N-F)  - 40dB - cover flange w/all thru holes -cover flange w/all thru holes

*For a Dual unit modify the P/N by adding a D to the end of the basic model #, the direction of the coupling and the coupling value of the second coupling arm.
Example: 750-308-dB-C3-C3 becomes: 750-308D-dBF-dBR-C3-C3
(where dBF= forward coupling and dBR= reverse coupling)
