The AS-419 “Bandpasser” contains six high performance bandpass filters in a single compact package and comes standard with filters for 160, 80, 40, 20, 15 and 10 meters. Filters for 160M thru 15M are 3-pole Chebyshev designs which provide over 40db rejection of adjacent bands (excluding WARC bands). Due to the narrow separation between 15M and 10M (25%), the 10M filter is a Cauer high pass design that provides notches on the 15M and 20M bands.
These filters are rated at 200 watts (100w over 2:1 SWR) and can handle 100% duty-cycle modes, such as RTTY, with ease. These filters are designed be used between your radio and amplifier or antenna. They low insertion loss (less than 0.6 db) and low SWR (less than 1.25:1) across an entire band. The filters can be selected via front panel pushbutton switches, via our 4-wire system or remotely by applying +12 for each individual band to the rear panel control connector.
