INSTALLATION
(1).
Mount
the EDX-2
to
the desired position. (Figs. 2&3 )
(2). Ground the EDX-2 grounding-terminal
an
independent wire as short as possible.
(3). Connect an antenna element
*to
EDX-2'santenna element terminal. (Fig. 1 )
(4). Connect the EDX-2'sco-ax cable
to
your
radio's
antenna terminal. (Fig. 1 )
(5). Connect the EDX-2'sco-ax cable
to
your
radio's
antenna terminal. (Fig. 1 )
you may extend the control and co-ax cables to the desired length. (co-ax impedance
is
50
n.
)
*Avoid undesirable antenna length (See p.3 )

•CALCULATION OF UNDESIRABLE ANTENNA LENGTH
Certain length
of
antenna element could be extremely
difficult
to tune with EDX-2, besides
causing high-voltage on the radio chassis.
Such lengths are dependent on
your
operating frequency, and can be calculated as follows.
rEXAMPLE ]Undesirable antenna length with an operating frequency
of
29.00MHz
