RTR-MXRTR-LSRTR-RMIRPA-T
Every HydroLynx transmitter, repeater and receiver carries an FCC narrowband-compliant radio matched to your licensed frequency. The RTR-MX serves data transmitters, the RTR-LS serves receivers and repeaters, the RTR-RMI ScadaLynx radio provides two-way SCADA links — and when a path is long or obstructed, the RPA-T amplifier boosts any of them from 5 to 20 watts.
Which radio goes where?
| Radio | Role in the network | Bands | Channels | Datasheet |
|---|---|---|---|---|
| RTR-MX Narrowband Radio Link | The RF link inside Data Transmitters | VHF 148–174 MHz | 16 (RX/TX pairs) | |
| RTR-LS Narrowband Radio Link | The RF link inside Data Receivers & Repeaters | VHF 154–174 · UHF 400–420 MHz | 8 (RX/TX pairs) | |
| RTR-RMI ScadaLynx Radio | High-speed transparent modem for two-way SCADA, polling & control with 50388 systems | VHF 132–174 · UHF 403–512 MHz | 1, field-programmable | |
| RPA-T Radio Power Amplifier | Boosts transmitters or repeaters that need more reach | VHF 136–175 MHz | 5 W in → 20 W out |
Specify your frequency at order time. Each channel carries a receive and transmit frequency pair; the pair can differ but must fall within the radio’s band. Packaged stations default to a Maxon 5 W radio with enclosure; Ritron 5 W and 30 W options are supported. Why we ask for your frequency →
