Installation
The PRO-TRI 88/136-174/216-… makes it possible to use only one antenna for the operation of three transceivers (one in each range). See the figure below. The antenna must be a triple-frequency antenna, i.e. it must be resonant on the actual frequencies in the three bands.
The transceivers may be used independently and will have no degrading influence on each other. Typically, the triplexer is installed next to the transceivers and only one cable is used between the triplexer and the antenna. The triplexer is suitable both for base station and mobile use.
The main tasks of the triplexer are to protect the individual receiver input from being destroyed by the transceiver in the contrary bands and to ensure a low-loss path between the transceiver and the antenna which is not loaded by the other branches.
The triplexer can be operated together with any set of transceivers operating within the 0 – 88 MHz, 136 – 174 MHz and 216 – 960 MHz frequency bands.
Note
* Temperature on box surface. Adequate cooling to keep max. temperature below +60 °C must be provided.
