SECURING TELESCOPING POLES TO DIRECTOR 1
NOTES:
Make sure while installing the CPVC with foam seal ring and black rubber coupler, that
the “THIS WAY UP” sticker is facing upward. This will align the slot in the foam ring to be fac
ing up inside the EST extension. This slot is to allow the element to breath and provide venti-
lation for any condensation that builds up inside the fiberglass poles.
To straighten the 30m/40m telescoping pole assembly the poles can be twisted inside the
EST extensions before the rubber boots are tightened. To check for straightness, sight along
the boom to check if the sweep assembly is aligned correctly.
To secure the telescoping poles to the Element Housing Unit, first slide a rubber boot over the
base section of the telescoping pole. Use
figure 3.15
for assembly.
Slide the CPVC Inner Support Tube assembly for director 1 (about 156” long), that you glued
in
figure 3.13,
inside a 30m/40m telescoping pole assembly as shown in
figure 3.15.
There will be no CPVC for the return side of the 30m/40m loop.
Slide the rubber coupler and foam sealing ring inside the EST extension. The rubber coupler
should align with the CPVC protruding out of the driven element housing.
Locate the SS hose clamp 016 (60-6000-15). Place the hose clamp over the rubber coupler
before fitting the coupler onto the driven element.
Once the rubber coupler is seated flush against the driven element housing and the “THIS
WAY UP” sticker on the rubber coupler is facing upward, slide the hose clamp up against the
housing and tighten. This will leave the Driven CPVC assembly protruding from the EST
extension.
Slide the 30m/40m telescoping pole assembly over the CPVC assembly and into the EST
extensions.
Slide the rubber boot over the metal ring on the EST extensions. The large hose clamp on
the rubber boot must slide over the metal ring on the EST extension.
The smaller hose clamp of the rubber boot should not slide over the locking ring on the tele-
scoping pole.
Once the rubber boot is in the correct location tighten both hose clamps. Due to cold flow of
the rubber you should re-tighten the hose clamps after 30 minutes.
Repeat the same process for all other poles on the driven element.
