Preselectors PS4-4(6)VA are based on bandpass filters and designed to pass several frequency channels and cut out the other.
Absence of wide variety of 300 MHz range equipment yet restrains active usage of this frequency range in the trunking systems.
PS4-4(6)A type preselectors, and other "ALT" range equipment: broadband dipole, directional antennas, filters, duplexers, transmitter combiners, enable you to construct highly effective 300-360 MHz communication system.
