MES 2000 series Band Reject Duplexers uses six Helical Resonators housed in extruded Aluminium cavities offering high 'Q' interconnected resonant cavities. Notch Pass Bandwidths from 50 KHz to 1 MHz wide are custom built. Semi-rigid coaxial cables are used in UHF and higher frequency bands to offer high Tx to Rx isolation. Field tuning is accomplished with silver plated tuning screws in the rear of the unit. The entire units is given a coat of epoxy paint for additional protection.
