This product is a 9-order series high-pass filter, the passband (@160 ~ 500MHz) insertion loss is less than 1.5dB, stopband (< 110MHz) insertion loss is greater than 40dB, the performance indicators are far better than other products processed using PCB bare board. Small in size and with a robust aluminum shield housing, it can be plugged directly into the antenna system. Powerful filter frequency signals below 140MHz, used for VHF (144MHz), UHF (433 ~ 470MHz) radio, receiver, can effectively suppress the interference of FM and medium and short wave radio stations. We can also design and customize other frequency filters according to customer requirements. (Note: This product is not waterproof, please do waterproof treatment for outdoor applications)
