SSB Electronics 1066-NF (MHP 600) Mast Mounted 6-Meter Preamps are extremely low-noise mast preamplifiers, suited for transmission pass-through up into the Kilowatt
range. Based on the LNA 600, the 1066-NF offers N-Type female connections and 2 high power coaxial relays.
Turning on the preamp is simply done by applying the operating voltage; after switching off the operating voltage, the MHP 600 is bridged for the transmit mode with a low 0.03 dB insertion loss.
The operating voltage is applied externally via Bias-T and a UHF (SO-239) socket placed in the middle between the N sockets on the preamp. It is absolutely necessary that a shielded cable such as
Model RG 58/U is used. The inner conductor has to be connected to the Plus (+) pole, and the shielding to the Minus (-) pole.
