Features 【Small Insertion Loss】: The filter can work in the range of 1 to 3000MHz, 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. 【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. 【Anti FM Interference】: When the stopband rejection is greater than 50dB, the filter blocks the broadcast FM band between 88‑108MHz, with a stopband of 76MHz to 120MHz.
