The SM3300 ‘combiner unit’ was specifically designed to enable two antennas to be connected to one transmitter to increase radio performance within a vehicle without the use of switching circuitry.
The passive unit can operate from 380MHz to 410MHz. With an insertion loss of less than -0.5 dB and isolation port to port of less than -30 dB this unit offers a great performance against active switch units.
This unit has also been employed for the use of combining two bumper mount antennas to one transmitter for increased performance.
