Make sure to attach the element to the element plate before
attaching the plate to the boom. This will help during the
assembly process.
Also make sure the mounting orientation of the housing in rela-
tion to the mast plate and other elements is correct.
The elements electrical center must be directly over the boom.
It is possible to mount the EHU’s the wrong way and the ele-
ments electrical center wont be over the center of the boom.
The electrical center is the 1/4” bolt mounted in the housing.
This is important to the performance of the antenna.
