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.
