BPF 3/...-200-SHT
Band-Pass Filter for the 130 MHz Band
DESCRIPTION
High power base station shortened band-pass filter for the 116 - 146
MHz range.
Due to the use of large ø200 mm cavities a high Q is achieved, resulting
in a very narrow passband.
The large dimensions also mean a high power rating.
The SHT-version has only 600 mm cavity length.
Unloaded Q of a single cavity is approx. 3000.
High frequency stability on temperature and power.
19” mounting brackets are available as an option.
