High Pass BCB Rejection Filter for Longwire Antennas
Type A Filter
This BCB (MW Broadcast Band) rejection filter is ideal when using a longwire or beverage antenna. It has similar performance characteristics to our standard BCB filter with the exception that the input coax connector is replaced with a banana type screw post for the antenna connection. Inside the enclosure is a special torroid transformer that provides the impedance match between the antenna and the 50 ohm input. This BCB filter is ideal for portables that provide an AUXILLARY antenna input (a high Z input). If the portable receiver includes a miniature headphone jack for the AUX antenna input, then the "Type B" model should be purchased. If you use a table-top receiver that has the standard SO-239 coaxial jack antenna input, then the "Type A" model should be purchased. Filter attenuation is similar to the graph below.
