Expandable Tx Combiners 935-940 MHz / 150 Watts
DB8062H

DB8062H combines 2 to 20 transmitter with frequencies as close as 250 KHz, with low loss and minimum insertion loss, for conventional and trunked services. It uses 5x 7x 12 inch (127 x 177.8 x 304.8 mm) high Q copper three-queater wave cavities with Serpentin� interconnecting and phasing cabling of half-inch (12.7 mm) low loss super flexible.

Special Design - Each cavity is temperature compensated and in bandpass configuration with sliver-plated N- female connectors.

Maximum Isolation - 150 Watts isolators with a 20 Watt load at input and a 100 Watt load at reflected port - mounted in the rear for better airflow -are connected to each cavity input port to assure maximum Tx-to Tx isolation.

High Q Bandpass - This characteristic provides a minimum rejection of 45 dB at receiver frequencies 45 MHz removed from the cavity's center frequency.

Power Rating - Up to 150 Watts continuous input power per channel. Total power output of all channels must be less than 600 Watts for H series. Optional high power connector available on L series for output up to 1200 Watts.

Factory Tuned and Field Expandable - The combiner can be retuned in the field with appropriate equipment. Each is shipped with performance data at the specified frequencies.
