DIRECTOR 1 EHU (continued)
ELEMENT SUPPORT TUBE (EST) MOUNTING - OVERVIEW
Figure 3.11
shows the detail for attaching the element support tubes (EST’s) to the Driven element mount-
ing plate.
Note the reinforcing tubes shown in
figure 3.11
—they are outlined in red to show their placement. These
tubes are placed on the outside diameter (OD) of the 1-3/4” fiberglass EST tube to keep the saddles from
crushing when the aluminum saddles are secured in place. This will be covered in more detail later in this
section.
