PRO-ISO-PHY-TETRA-S2

Two-TETRA-Station Combiner
Description
  •  
    • The PRO-ISO-PHY-TETRA-S2 combiner provides the possibillity of connecting up to two TETRA radios into one common antenna.
    • The PRO-ISO-PHY-TETRA-S2 models are available in the frequency range 380 – 470 MHz (on request).
    • 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 compliant connection of two digital radios.
    • The PRO-ISO-PHY-TETRA-S2 is the successor to the PRO-ISO-PHY-TETRA-2.
    • The PRO-ISO-PHY-TETRA-S2 has improved isolation between the ports more than 62 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.
    • 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
