Hi-Z 75 ohm Inline Preamp


     This 75 ohm cable amplifier was designed to be used as a system amplifier for 160 and 80 meter receiving antennas. Its primary purpose is to provide a precision termination for typical antenna array controller/combiners. In typical operation this amplifier would be connected to the output of an array controller providing precision termination and 15dB. of voltage amplification. Nominal input impedance is 75ohms when the output port is also terminated in 75 ohms.
