*Model 3004 has frequency sensitivity of ±1.2 dB from mean coupling. The mean coupling may deviate from the nominal by ±0.4 dB.
NOTE: Model 3004 Series is available on a Special-Order basis. Minimum quantities may apply.
ORDERING INFORMATION: Specify model number and add dash number suffix for nominal coupling in dB.
