The EME181 Series RX bias tee Kits are suitable for powering receive only Pre-amplifiers from 50MHz to 1.2GHz via a coaxial cable. All Kits have been optimized to cover each specific band, for the lowest loss and return loss. The board is fitted with PTC protection to safeguard against any short circuits on the RF/DC output.  For wide band use with scanning receivers, select the 430MHz version.
