CHAPTER TWO
SECTION 2.1
MOUNTING THE EHU’s ON THE BOOM (continued)
EHU WIRING (continued)
Check to be sure the terminal plug is firmly inserted into the terminal header.
Lay the control cable wire inside the wire tray of the EHU as shown in
figure 2.16
. This trough acts as
a strain relief so that the cable will not be pulled out of the EHU. It is a good idea to leave a small
amount of slack between the plug and the point which the tray starts as shown in
figure 2.17
.
Using the coax seal and cut into 1 inch strips as shown in
figure 2.18
. You will need three strips. The
remainder can be used to seal the driven element SO239 connectors, should you wish to.
Apply coax seal on top of the control cable and work it around the cable and on top of the cable tray as
shown in
figure 2.19
. This will help keep water from entering into the EHU. Apply the coax seal to the
2 remaining sections of the wire tray as shown in
figure 2.20
.
Repeat wiring and coax seal preparation for each EHU. When finished, the EHU’s will be secured to the
aluminum element mounting plates. This is covered in detail in the next chapter.
