2. OPERATING CONTROLS
(continued)
GROUND LUG/TUNABLE RADIAL
UNIT MOUNTING HOLE
The .437 dia. (7/16”) hole for either the
included Ground Lug shaft with hand
locking knob or optional Radial Reel Unit
(PN 06401) mounts here. If the optional
Tunable Radial Unit is not used, fixed
length radials must be connected to the
Ground Lug Shaft.
RADIAL RELEASE KNOB
This knob has two functions, it locks the
Radial Reel shaft in any direction allowing
you to “point” the radial in the desired
direction and lock it. It also allows you to
remove the Radial Reel or the Ground Lug
by backing the knob out far enough to
disengage from the groove in the shaft
allowing the shaft to be pulled out. Make
sure the Radial Release Knob is tight during
operation to ensure radial electrical
connection.
WIRE REEL LOCK/DRAG
Locks the vertical radiator reel shaft, this
will keep the Wire/Cord from unwinding
during transport and storage. The amount
of drag is easily controlled by this knob as
well.
CORD REEL HOOK
Allows easy attachment / detachment of
the leader cord loop.
ANTENNA CONNECTOR
Connect 50-ohm coax terminated with a
PL-259 connector to this SO-239 connector
located on back of main unit. (See picture
below)
