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.

Key Features

  • Integrated Single-Antenna Solution: Enables simultaneous transmit (TX) and receive (RX) on a single antenna, significantly reducing tower loading and cabling costs.
  • Optimized VHF Bandwidth: Precision-engineered for the 144–160 MHz range, covering critical public safety and commercial frequencies.
  • Low Insertion Loss: Minimizes signal degradation to ensure maximum transmit power and receiver sensitivity.
  • High Isolation: Provides robust frequency separation to prevent transmitter noise from overpowering the receiver.

The Mitt is it.
I ordered the applicator because the Poli Glow Kit on hand was ordered and received a couple of years ago and it had the old chamois covered rectangular applicator. I could tell by looking that the mitt was the better solution. Also, the mitt was described well in an online video, so using it was easy to learn. The results were fantastic and I am very pleased with it. The only thing I would change is to add some more information on how often to replenish the mitt and with how much Poli Glow liquid. I wasn't sure if I was skimping or wasting the material. As I approached halfway, I couldn't tell if I was going to run out before I finished, so I tried to be as frugal as possible. Turns out, I had liquid left over.
