The parts explosion drawing in figure 3.20 gives you an overview of the assembly of the director EHU.
Detailed instructions follow.
NOTE: If you have purchased the optional boom truss, be sure to refer to Chapter Ten before assem-
bling and mounting the Director and Reflector EHU’s. Even though the installation of the boom truss
does not take place until the DB18 Yagi is nearly completed, there are two truss attachment plates (PN
10-1607-01) that need to be installed while working in Chapter Three.
