RF combining systems allow multiple transmitters to share the same antenna, maximizing tower utilization, reducing tower loading and reducing interference risk. Bird is known for highly specialized technical expertise in providing system designs for simple applications as well as the highly configured applications. Designs may be for a simple antenna system or a multiple antenna system with challenging frequency plans.

Control Station Combiners
Bird Multi-Channel Control Station Combiners provide frequency-agile operation across their entire frequency range in a very small 1RU form factor
Star Junction Combiners/Multicouplers
Star Junction Combiners/Multicouplers provide design security for any multichannel radio system. From the most complex multi-site Homeland Security system to the simplest 2-channel private system.
Airline Junction Combiners

Bird Airline Junction Combiners can be configured for 2 to 6 channels. High performance specifications with narrow adjacent channel spacing and low insertion loss. The design uses 5.8” square cavities in a 19” rack mount configuration for space efficiency.

T-Pass Transmit Combiners
Each T-Pass Transmit Combiner system is designed and configured for the specific site at which it is to be used. Easily expandable when channels need to be added at a later time.
