Comet CF-360B Duplexer – HF/VHF/UHF Band Splitter

The Comet CF-360B is a high-isolation duplexer designed to separate or combine signals across HF and VHF/UHF bands. Ideal for transceivers or antenna systems operating in the 1.3–30 MHz and 49–470 MHz ranges, it ensures minimal loss and maximum performance across amateur radio setups.

Key Features:

• Dual Band Filtering:

  • Low Pass Port: 1.3–30 MHz

  • High Pass Port: 49–470 MHz

• High Isolation: ≥ 45 dB between ports to prevent cross-band interference

• Low Insertion Loss: ≤ 0.2 dB (HF), ≤ 0.25 dB (VHF/UHF)

• High Power Handling:

  • 600W PEP (HF)

  • 500W PEP (VHF/UHF)

• Impedance: 50 Ohms

• VSWR: ≤ 1.2:1 for optimal signal transfer

• Connectors:

  • 2 × SO-239 (female)

  • 1 × PL-259 (male)

• Compact Size: 66 × 90 × 26 mm

Applications:

• Combine HF and VHF/UHF radios into a single dual-band antenna.

• Split dual-band transceivers into separate HF and VHF/UHF antennas

• Reduce intermodulation and TVI with precision filtering

Connector Notes:

“MP-MJ” and “MJ” refer to standard PL-259 male and SO-239 female connectors, ensuring compatibility with most amateur radio gear.
