CD324-8DB Model 8 dB FM IBOC Hybrid Injector

The CD324-8DB is intended for use by FM radio facilities increasing IBOC injection to -14 dB (4%). The CD324 design is based on the field proven 10 dB FM IBOC Hybrid Combiner used extensively in early IBOC FM field trials. By reducing the coupling level to 8 dB the amount of digital power lost to the system reject load is reduced, while the analog power loss increases slightly.

The 8 dB Injector Hybrid is intended for those FM facilities that are running at low transmitter power levels and have an interest in increasing their IBOC effective radiate power level to the recently authorized -14 dB power level.

Features and Benefits

  • Easy Installation
  • Use existing transmission line
  • Lower digital insertion loss versus 10 dB hybrid injector
