15
This option does not enable 6 meter band. It is used to tell controller that antenna
has optional 6 meter passive element. If 6 meter Passive Element Kit is installed
on antenna, select “Yes” with
K2 knob
and press
Select
button. The lengths for
the 6m passive element will be active for the
NORM
and
180
positions in the
frequency range of 50 through 51 MHz. On 6 meters with the aluminum element kit
installed, the
180
mode will not function on that band. The
BI 3/4
mode will
dramatically reduce the front to back, but the antenna will still have some forward
gain. This does not affect any other band.
Remote Driver Option
This option requires optional remote driver board kit. If using optional remote driver
board it must be enabled by selecting “Yes”. This tells controller to use remote
CAT-5 port at rear of controller to communicate with driver board instead of board
inside controller. The driver board in controller housing is still required to power
controller and to communicate with remote driver board. The OptimizIR can be
used in normal stand-alone mode just by turning off remote driver option.
Power Off Retract
This option determines whether or not controller will automatically power off after
elements are retracted when
RETRACT
button on controller front panel is pressed.
Display Metric
This option sets units to be metric or not when displaying element lengths. This
only affects Create/Modify menu item.
Global Correction Factor
This option allows changing element lengths over a range of +/-2.0% and affects
element lengths on all bands and modes (
NORM
,
180
,
BI 3/4
). If a correction
factor is only needed on some bands, there is a per-band setting available in
Create/Modify Mode
.
To change correction factor, use
K1 knob
to adjust value of correction factor. Use
K2 knob
to select which setting to change. Press the Save button to store new
setting and make antenna tune to new lengths.
In some weather conditions (e.g. ice freezing on fiberglass tubes), it may be
necessary to change default lengths for elements by a small correction factor to
bring antenna tuning and SWR back into normal range. Any water, snow or ice on
elements is going to make elements act electrically longer, moving antenna’s
resonant frequency down. Since all elements are affected equally simply applying
