The MHP 200 is an ultra low-noise Masthead-Preamplifier with coaxial relay changeover capable of handling SSB RF-Power levels of up to 1500 Watts (750W on CW).
The integral coaxial-relays have succesfully been tested up to 2 KW SSB and feature large goldplated contact areas with extremely low insertion loss (0.1dB). Double shielded Teflon coaxial cables are used in order to guarantee a low losses and a high power handling capability.
There is no RF-VOX and protection circuits in the MHP 200 so a sequencer such as the DCW 2004B or amplifier with integral sequencer MUST be used.
Power is supplied via a separate 13.8v supply to a UHF socket between the twp N-Type sockets on the underside of the unit.
