K9DP QRP AM Broadcast Interference BCI Filter Male/Female BNC - Compatible with Xiegu X6200, X6100, X5105, G90, G106, SDR receivers, HF Amateur Radios

The K9DP QRP broadcast interference (BCI) filter allows QRP (low-power) amateur radio operators to reduce or eliminate unwanted broadcast interference in their signals. Primary designed to help HF radios and receivers that struggle with front-end overload from AM broadcast stations, compatible with Xiegu X6100, X5105, G90, G106 and SDR receivers. This lightweight and portable filter is ideal for use in field operations such as Parks on the Air (POTA), Summits on the Air (SOTA), and Field Day. It has been tested at power levels up to 20 watts with SSB, CW, and digital modes, and its small size and low weight make it easy to take with you wherever you go.

Measuring only 3.4 inches (86mm) in length and weighing just 30 grams, it's a convenient choice for on-the-go operations. Overall, this filter is a great way for radio operators to enhance their radios performance and improve their communication experience. These filters have a 50 impedance and are symmetrical, so it's not important which end is the input or output.
Caution: High SWR can damage the filter. The filter should be inserted inline between the transceiver and tuner, rather than between the tuner and antenna. If your radio has an internal tuner, be sure to use a resonant antenna or an antenna with a matching circuit, such as an EFHW (end fed half wave), in combination with the filter.
