System Overview & Operational Purpose
The Jotron Antenna Changeover Unit can be used in several applications, either as external main/stby radio switch or a main/stby antenna switch. The unit is 14 TE wide and is mounted in a 19ââ sub-rack (can room ex. 6 units). Jotron Antenna Changeover Unit is basically a RF relay with control circuit, interface and internal power supply.
The RF relay has three connectors (common, NC (main) and NO (stby)). The unit can be hot wired to the alarm outputs from the radios, or controlled from a remote control unit. For maximum flexibility the input signals are optocouplers that covers a large voltage range. In addition, the control logic can be inverted. The unitâs several outputs can be used for monitoring the current status or controlling external units.
