Multiband Antenna VA56

Multi-Element Antenna for CAB Radio

Multiband Antenna VA56

  • Multiple radio communication systems integrated into a single antenna element with a low-profile omnidirectional design.
  • Optimized location of 160 MHz and 450 MHz radiating elements.
  • Enables use of all Rx & Tx radio bands simultaneously.
  • Independent channels for GSM-R radio and GSM public/data transmission.
  • Radiating element covers GPS, GLONASS, Galileo, and BeiDou.

The VA56 is a multiband railway antenna for mobile communication with a low-profile and omnidirectional design. It has multiple radiating elements, each with its own connector output.

The antenna‘s 160 MHz and 450 MHz radiating elements are optimally located to achieve maximum output-to-output isolation, allowing for simultaneous use of all Rx & Tx radio bands. The 160 MHz band can be tuned for optimal performance or to compensate for antenna installation variations.

The dual independent GSM radiating elements provide simultaneous channels for GSM-R radio and GSM public/data transmission (UMTS, WiFi, etc.). The GNSS radiating element covers GPS L1, GLONASS G1, Galileo E1, and BeiDou B1, with a pre-filtered low-noise amplifier to suppress out-of-band signals and maintain low-noise GNSS signal reception.
