Once you have all the elements on in the correct location, check the alignment of the elements on the
boom sections. Element locations are given on the top of the diagram above. You may use this to verify
correct tube overlap between sections and that the booms are assembled correctly.
Rotate the sections to align the elements if needed and re-tighen the clamps.
Boom to Mast
Select the parts shown and install the mast plate onto the boom. The mast plate should be installed
on to the largest section of the antenna (boom section #3) . You may balance the boom
by installing the plate at the center of gravity of the antenna. You can determine this point
by simply holding the antenna and balancing it in your hand. Make sure the elements are in correct
orientation before tightening the U-bolts. Do not allow the mast plate to come within 1 inch of the
elements on that section.
