Our Control Station Combiners (CSC) is an ideal solution to reduce the number of antennas required on a communications site by maintaining a high radio-to-radio isolation at all times. It can significantly reduce tower clutter and loading, and simplify cabling installation at control center facilities. This product provides frequency-agile operation across a frequency range from 746 up to 869 MHz covering the public safety bands 700 and 800. This combiner has the possibilities to be connected to two antennas TX and RX. In case of only one antenna is used for TX and RX, an external duplexer is required. This unit is also available in 8, 12, 16 and 32 ports configuration. DOWNLOAD PDF -
Comprod is a leader in the design of RF filtering and coupling devices. The following are the specifications for couplers and tuners required as part of a disguised antenna solution.
- Broadcast couplers - allow AM-FM broadcast receiver operation along with normal two-way mobile radio operation.
- Crossband couplers - allow mobile radios on two different bands to operate with a single disguised antenna.
- Antenna tuners - provide impedance matching and partly retuning the existing antenna to new frequencies.
-
Designed to meet customers' special requirements
- Two or three separate frequency segments in a given mobile band
- Cross-channel operation in two mobile bands with one antenna
