The MSC Tx combiner uses dual stage isolators and hybrid combining techniques to provide Tx-Tx isolation and to minimise intermodulation (IM) impacts. The Rx system uses an ultra low noise preamplifier with user-selectable gain and excellent 3OIP performance, with a multi-way output divider to ensure optimum system receive sensitivity is available. Integral high quality bandpass filtering provides high Rx selectivity and Tx-Rx system isolation performance. Form-C relay outputs provide alarm notification of DC power or Rx LNA amplifier failure. The MSC is available in sub-bands covering VHF, UHF and 800MHz frequency ranges.
