Optional, external diplexers are available, including the FM34-Series of diplexers that can provide up to 85 dB of isolation between the VHF/UHF and L-Band frequency ranges while minimizing additional insertion losses.
The CNI24 Series has been designed for deployment on high performance (MACH 2.0+) aircraft. The -12, -15, and -17 broadband models have been designed to support interferometer-based DF applications and are phase-matched on a 100% basis.
