PRO-ISO-PHY-TETRA-S-ELW

Two TMO TETRA Mobile-Station and one DMO TETRA Mobile Station
Description
  •  
  • The PRO-ISO-PHY-TETRA-S-ELW combiner provides the possibillity of connecting two TMO and one DMO TETRA radios into one common antenna.
  • All PRO-ISO-PHY units are designed for single carrier signal per port and thus it is not recommended to add a multiple carrier signal on the input ports, as this could potentially create unwanted intermodulation products transmitted on the antenna port and reflected on the input ports.
  •  
  • ETSI and DIN-SPEC 14507-2 compliant connection of two digital radios.
  •  
  • The PRO-ISO-PHY-TETRA-S-ELW supports Direct Mode Operation (DMO), giving one TETRA mobile radio the ability to communicate in direct mode.
  • The PRO-ISO-PHY-TETRA-S-ELW is the successor to the PRO-ISO-PHY-TETRA-ELW.
  • The PRO-ISO-PHY-TETRA-S-ELW has improved isolation between the ports – more than 60 dB – and lower insertion loss.
  • The use of high-quality system components such as highly selective helical duplex filters and high-performance isolators provides high isolation and secure communication.
  • Built-in high-pass filter, for attenuating interference from 150 – 174 MHz and 74 – 87.5 MHz bands.
  • The smallest and most compact design on the market.
  • Suitable for both stationary and mobile use.
  • Also available in tray for 19″ rack mounting.

  • Vibration and shock tested in accordance with EN-60068
