Refer to figure 4 and figure 5 and start the assembly of the parasitic elements
6- Assemble one push nut on each of the parasitic elements of both groups (labeled A-H)
using the
provided tool
. Slide the push nut until it reaches the first mark on the element (see figure 4.)
WARNING
:
If you passed the mark, do not try to slide the push nut backward. Sliding the
push nut backward will tend to damage it, instead slide the push nut all the way off then reinstall
it.
Note
: Extra push nuts are provided for replacement of damaged ones.
Note : for section 7 and 8 refer to figure 1, figure 4 and figure 5 while assembling
7- Insert element "A" ( black end ) from GROUP 1 into its
designated hole in the boom, as shown in the figure on the inside
front cover. Assemble another push nut from the other side ( see
figure 4 and figure 5 ), and slide it until it reaches the 3/16" black
insulator. Make sure that the element is secured in place with
minimum free play .
8- Repeat the previous procedure for the remaining elements
from GROUP 1 and GROUP 2. See inside front cover and figure
1 for full detail on hole positions, elements locations, color code,
and alphabetical label.
9- After installing all the parasitic elements, insert the U-bolt in
its designated holes keeping in mind the polarization of the
antenna (see figure 6).
