Reception on up to three frequency bands simultaneously
The A1 is a ground sector antenna designed to provide approximately 60° of coverage. The A1 is lightweight and easy to mount on buildings or the side of a tower. The A1 is designed to be installed around a structure to create an overlapping high-gain reception system. Multiple A1s can be used to form a 360° diversity antenna system capable of up to 15dBi of gain in any one direction when positioned correctly.
The A1 can be purchased in either single or multi-band versions. It incorporates a high-performance down-converter that has exceptional selectivity and noise figure characteristics. This enables the A1 provide a UHF output regardless of the input frequency. Power for the A1 is provided through coaxial cable that connects the antenna to the diversity receiver.
The output of each antenna is fed into Troll Systems’ packet diversity networked receiver the DMR 8000. A two to eight input diversity receiver with a touchscreen interface, the DMR8000 is designed to perform all the packet switching, decoding, transcoding and routing. Troll’s new DMR series receivers provide two to eight antenna inputs that can be deployed individually or daisy chained together to increase the number of unique data streams an A1 sector can decode.
