The 4 element antennas have two directors, Director 1 and Director 2. See the installation
manual to determine the location of each on the antenna. The 2 element and 3 element
antennas will also display Direct 2 even though they have only one director (Direct 1). Make
sure you select the correct one. We did this to make our software compatible across our
entire product line.
D1
= Director 1
D2
= Director 2
DVR = Driven
REF = Reflector
To scroll across through the different elements use the
BAND
up or down button. Hit the
select button once the desired element is flashing. This will allow for adjustment for each
individual element. Use the
BAND
up and down arrow to change the lengths of the element.
Note that the TUNING light will flash as you move the element. When you are finished mak-
ing all adjustments, press the up or down arrow until DONE is flashing again, and press the
select button. The screen will read “SAVE? YES NO, with NO flashing. Use the up or down
button to make the proper choice (“YES” or “NO”) and press the select button. If you select-
ed “YES”, the new lengths will be saved into memory for the ham band or frequency range
you are currently on. After saving your new antenna the controller will scale it and use it
throughout the entire ham band or frequency range you created it in. If you create a new
antenna or modify the factory default antenna in any of the range segments the controller will
then scale that antenna throughout the selected frequency range and only the selected
range. Creating and modifying an antenna anywhere (it is best to chose a frequency near the
bottom of the range) in a frequency range will change the entire range.
You can create the antenna at any frequency within the ham band or general frequency seg-
ment. For the very best results model the new antenna in the middle of the band or frequency
segment and set the controller to that frequency before creating the antenna. The frequency
coverage range of each of our antennas is broken up into numerous blocks for each direction
(
NORM, 180 degrees, and BI (3/4)
), each covered by a different antenna model (
Figure 1
).
Using the create antenna mode you can modify and save any of the master antennas (
Figure
1 & 2
). The frequency range is identical for the all three direction modes of the antenna
(
NORM, 180 degrees, and BI (3/4)
). If you select “NO”, no changes will be made, your
antenna segment will be just as it was before.
