Description
Motorola 9175300H02
VHF Internal Duplexer (144–160 MHz)
Seamless Single-Antenna Repeater Operation
The Motorola 9175300H02 is a high-performance, RoHS-compliant internal VHF duplexer designed for professional repeater systems. A duplexer is a critical component in radio infrastructure that allows a repeater to transmit and receive simultaneously through a single antenna. By isolating the high-power transmit signal from the sensitive receiver, the 9175300H02 prevents desensitization and interference, ensuring clear and reliable two-way communication across your entire coverage area.
Tuned specifically for the 144–160 MHz frequency range, this duplexer is engineered for seamless integration into Motorola’s premier repeater lines. Its compact, internal-mount design allows for a clean, professional installation within the repeater housing, eliminating the need for external shelf-mounted components and reducing the overall footprint of your radio site. This is an essential upgrade for organizations looking to simplify their antenna systems while maintaining peak digital and analog performance.
