3.2.4.2 Long Wire Connections
The long wire connection starts from two lugs on the back panel
labeled ‘Longwire.’ They correspond to antenna selection switch 2
on the front panel. An RF ground connects to the lug labeled RF
GND. When using a single wire ‘counterpoise, it should be 5-10%
longer than the random length long wire.
IMPORTANT NOTE: A long wire connected at the back will be
radiating from the moment is leaves the MAC-200. This can lead
to excessive RF levels within the radio room at even modest power
levels. The length of wire within the radio room needs to be kept to
a minimum.
