FOR MORE THAN 8 TRANSMITTERS:
1. Using the supplied BNC-BNC cables, connect the ANTENNA
OUTPUT of each transmitter to the ANTENNA INPUTS of the
PA821.
2. Use the 1 ft. jumper BNC-BNC cable to connect the MAIN
OUTPUT
of the PA821 to the A IN of the EXPANSION PORT.
3. Connect another
ANTENNA OUTPUT (from a ninth PSM trans-
mitter, second PA821 or other antenna port) to the
B IN of the
EXPANSION PORT.
4. Attach an antenna to the A + B OUT of the EXPANSION PORT.
For wideband applications, use the PA805WB directional antenna,
