ANTENNA ASSEMBLY
1.
Locate the 6’ boom section and, using a permanent marker (refer to Figure 1), place a mark 2 ¼”
from one end of the boom
– this is the Reflector point. All further measurements are made from
this end of the boom. Next
, place a mark at 42 ¼” – this is the Driven Element point. Next, place a
mark at 34
¼” – this is the center line of the boom-to-mast plate. Last, place a mark at 69 ¾” – this
is the Director.
If this DSE3-
50 has the rear mount option, place a mark 3 7/8” from the end of the main boom.
Slide the 12” piece of 1 ½” tubing to this line, with the slits over the boom.
