Preselectors PS5-4(6)V are based on bandpass filters and designed to pass several frequency channels and cut out the other.
PS5-4V type preselectors are essential for every modern trunking communication station. Combine them with broadband antenna and receiver distribution panel and you will get finest repeater receiving section antenna system.
Addition of new cavities (model PS5-6V) enables to enlarge bandwidth during communication system growth and increase in number of channels.
