3.2.10 Cavity combiner
Combiners are used for combining several transmitting signals to a common transmitting
antenna. The transmitters are decoupled from each other so that no mutual interference
can occur.
The cavity combiner is used in DIB-R5 advanced for loss-free coupling of up to four car-
rier signals at one transmitting antenna. The cavity combiner is motor-tuned and allows
remote frequence changes.
The following figure shows the rear view of the cavity combiner. The following table
describes it in detail.
