SATELLINE-3AS VHF is a half-duplex VHF radio modem that operates on 135 … 174 MHz or 218 … 238 MHz frequency band. Channel spacing 12.5 and 25 kHz are available, with over-the-air data rates 9600 bps or 19200 bps, respectively.

A special advantage of the VHF frequency band, is the wider coverage. With the same carrier power and antenna gain, the connection ranges are 30 to 50 per cent larger than those reached with an equivalent UHF radio modem.

The radio modem is compatible with the most widely used serial interfaces RS-232, RS- 485 and RS-422. The SATELLINE-3AS(d) VHF with 5 W output power and a heat sink is the appropriate choice when continuous transmission (when transmitter duty cycle exceeds 20%) is required. In mobile fleet management applications, use of VHF frequencies reduces signal fading significantly

The product is available with and without display and with or without a cooling part.

The model SATELLINE-3ASd VHF is equipped with a LCD display, which facilitates easy programming of the radio modem.

Benefit from the SATEL NMS

A SATELLINE-3AS(d) VHF network consists of remotely adjustable radio modems controlled through the master station by the SATEL NMS (Network Management System) software. The SATEL NMS provides a powerful graphical tool for designing and monitoring the radio network.

  • The NMS radio modems monitor the condition of the radio connection, in particular the strength of the signal (RSSI), the voltage level of the power source and inside temperature of the modem. The information is transmitted to the software, where it is stored and displayed as logs and trend data. With the help of the graphical display at the software, the user can conveniently configure, add or remove radio modems as well as set repeater links, without need of a terminal.

Other benefits of the NMS:

  • Enhanced reliability through advance indication of anticipated faults and failures
  • Reduced configuration and maintenance costs through remote configuration
  • Flexibility in adapting to customer protocols and applications
