Instal the tubing in the locations shown.
The tubing can be identified by the lengths
given on the left side of the diagram.
This is the total length of the tube.
The element lengths are given from the
center of the boom to the tip of the tube.
For the driven element, the distance is
from the center of the boom to the outer
edge of the loop end. Slide a #4 hose
clamp over the loop ends before installing.
Verify the measurements and tighten the
clamps on the reflector and directors.
Leave the clamps on the loop end loose.
The loop end needs to move for final tuning
of the antenna. Install the 7/16 tube caps
on the ends of the elements.
