The MHP 600R is an ultra low-noise Masthead-Preamplifier with coaxial relay changeover capable of handling SSB RF-Power levels of up to 1500 Watts (750W 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 600R so a sequencer such as the DCW 2004B or amplifier with integral sequencer MUST be used.
