Once you have all the elements on in the correct location, check the alignment of the elements on the
boom sections. Check the distance between the elements that have boom joints between them. If the
insertion depth is not correct then move the boom to make these measurements correct.
Rotate the sections to align the elements if needed and retighen the clamps.
Boom to Mast
Select the parts shown and install the mast plate onto the boom. 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. The other option is to put the
plate in the physical middle of the boom. This will balance the wind load on the antenna.
Make sure the elements are in correct orientation before tightening the U-bolts.
