Coaxial Cable Connection
Connect the suggested 75 feet of coaxial cable (
DXE-8XDX075
) to the SO-239 on the rear of the
Remote Multi-Band Center Section as
shown. Run the coaxial cable (and the
control cable) at a 45 degree angle from
the rear of the antenna as shown.
Run the
coaxial cable (and the control Cable) at
a 45 degree angle from the rear of the
antenna as shown.
Connect the coaxial cable to your
transceiver RF output. Transceivers that
have an internal tuner should be able to
handle any slight mismatch with no
problem.
Manual Center Section Band Switching
When using the Manual Tune Center Section (
DXE-TW-
2010L
) select the band of operation by inserting the two
jumpers in their appropriate holes (one in the top band
selection and one in the bottom band selection).
Make sure
the power is OFF and there is no RF being transmitted!
The Jumpers have banana plugs on the ends and plug into
the printer circuit board. Make sure they are pushed in all the
way. There are two jumpers - one for the top part of the
antenna and one for the bottom part of the antenna. Both of
the jumpers must be plugged in and
must
be on the same
band.
Fine Tuning
Even though the antenna center sections (all models) are factory tuned, you may find that additional
tuning may be required for your particular installation.
Some minor adjustments may be necessary to
tune the antenna to the desired center frequency for each band. Check the tuning of the antenna using an
antenna analyzer before performing the tuning process.
Tuning is accomplished by varying the
distance between the turns on the coils internal to the center section.
A quality antenna analyzer should be used, not your transceiver’s SWR meter. Disconnect the
coaxial cable from the transceiver.
