The MBD-JMP jumper furnished with the amplifier allows the user to select either port three or
port four as the output port. However, if it is desired to provide signal output to both ports,
three and four, then the proper output splitter must be installed. Installation of the MBD-SPLT
splitter provides equal output at ports three and four. If unequal outputs are desired, use of the
MBD-DC, a 10 dB directional coupler, is required. It can be installed to provide a high level
output at either port three or four and a 10 dB lower level at the other. The tap port, and
therefore the lower level, is indicated by the arrow on the MBD-DC circuit board and is shown in
Figure 7.
