This is the most "cavity" resonator, manufactured by our company. Initially designed for aircraft range 118-136 MHz low-loss transmitter combiner, it has "settled down" in commercial range, also. It is successfully used for filtration of paging transmitters signals and receiving lowest loss during channel multiplexing of tranking repeaters with low frequency separation, due to its highest Q-factor (900 @ -1.0 dB).
