PROCEDURE FOR SECURING TELESCOPING POLES TO THE DRIVEN ELEMENT
NOTES:
Make sure while installing the, CPVC with foam seal ring and black rubber coupler, that
the “THIS WAY UP” sticker is facing up. This will align the slot in the foam ring to be facing
up inside the EST extension. This slot is to allow the element to breath and ventilate any con-
densation 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 20
for assembly.
Slide the CPVC Inner Support Tube assembly for driven element (about 156” long), that you
glued in
Figure 18,
inside a 30m/40m telescoping pole assembly as shown in
Figure 20.
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 sticking out of the driven element housing.
From kit the 49’ Element hardware kit (72-0023-01) locate the SS hose clamp 016 (60-500-
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 up, slide the hose clamp up against the housing
and tighten.
This will leave the Driven CPVC assembly hanging out of 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 be slid over the metal ring on the EST of the EST extensions.
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.
