Comet CFX-514J Triplexer 1.3-90/130-200/380-500 MHz RF Signal Combiner and Splitter with 55dB Isolation for Multi-Band HF, VHF & UHF Antenna Systems

The Comet CFX-514J Triplexer is a precision engineered RF signal combiner and splitter ideal for the amateur radio operator, communication professional, or antenna system integrator seeking reliable multi-band performance. This triplexer covers three essential frequency ranges spanning from 1.3 to 90 MHz, 130 to 200 MHz, and 380 to 500 MHz, enabling simultaneous use of HF, VHF, and UHF bands through a single coaxial feed line. Advanced band-pass filtering technology ensures high isolation of 55 dB between the low, mid, and high ports, significantly reducing the potential for cross-band interference while maintaining signal integrity. Low insertion loss across all supported bands preserves transmitter power and receiver sensitivity, allowing for efficient RF performance even in demanding communication environments. All connection points are equipped with standardized SO-239 UHF-style female connectors that provide a secure and robust interface with coaxial cables and radio equipment. The unit’s compact mechanical design simplifies the integration into base stations, repeater sites, or portable setups without taking up excessive space. With power handling capabilities up to 800 W peak envelope power on both HF and VHF bands and 500 W on the UHF band, the CFX-514J accommodates high-power rigs, multi-transceiver arrays, or shared feed line configurations without compromising performance. This versatility makes it an indispensable component in multi-band antenna systems, where reducing cable runs and streamlining station organization are essential. Whether you are transmitting on multiple bands, combining separate radios into a shared antenna, or deploying a streamlined feed line up your tower, the Comet CFX-514J Triplexer delivers reliable, high-quality RF performance
