Features Anti FM Interference: When the stopband rejection is greater than 50dB, the filter blocks the broadcast FM band between 88‑108MH, with a stopband of 76MH to 120MH. Filter Out FM: This band stop filter can filter out FM, prevent the short wave from being affected by it, and ensure the purity of its wavelength. Small Insertion Loss: The filter can work in the range of 1 to 3000MH, and the passband insertion loss is less than 1dB, which is very suitable for work use. Mini Size: This filter module is very small in size, compact in design, easy to carry, easy to install, and easy to operate. PCB Board: The PCB circuit board inside this filter module is exquisitely crafted, responsive, practical and durable.
