NOTES:
Spacing of the element in relationship to each other is very critical. Take great care in
making sure the elements are mounted a shown in
Figure 3
. All dimensions are taken from
the center of the element. This point is at the center of the fiberglass tube in both the EHU
or Return EST.
With the boom completely assembled, use a marker and a tape measure to mark where the
center of the elements will be. These marks will act as a guide for element placement while
assembling the antenna.
Take note in the orientation of the housings and how they are
facing in comparison to the boom.
For example with the 30m/40m housing's (REF, DVN
and DIR 2) pay close attention to the orientation of the EHU boxes when mounting them onto
the boom. They must be EXACTLY as shown in
Figure 3.
The REF and DVN are mounted
so the housing is outside of the sweep but the DIR 2 is mounted the opposite way. This is
critical for achieving the best possible performance from the antenna.
