Attach the Fiberglass Element Support Tubes to the Element Housing Units
The butt ends of the green fiberglass poles may vary slightly in outside diameter. Some of them may
have been sanded, while others were not. The colors at the ends will be either natural, or black. The
difference in colors has no affect on performance. Do not be concerned if they vary slightly in tight-
ness when being installed on the EHUs. This is normal. All poles are tested at the factory prior to
shipping, however in the event the pole just won’t fit sanding it is okay.
The EHTs on the EHUs have aluminum reinforcing rings attached to provide extra strength in high
wind conditions (Figure 15).
Locate the six rubber boots and repeat the following procedure for each of the six fiberglass poles.
•
Place the narrow end of a rubber boot onto the butt end of an EST. Slide it about 6” out onto the
EST (Figure 17).
•
Insert the butt end of that EST into one of the EHTs on an EHU, as shown in Figure 19. It is very
important to ensure that the butt end of the EST firmly bottoms out inside the EHT. Make
sure the EST is seated all the way into the EHT. Then push the rubber boot firmly onto the EHT
until the hose clamp is past the aluminum ring and will clamp down onto the fiberglass EST. The
correct mounting position of the rubber boot is shown in Figure 21. It is imperative that the
stainless steel hose clamp be located so that the clamp on the outside of the rubber boot on the EHU
side of the connection is completely past the aluminum reinforcing ring. This ensures that the hose
clamp can grip onto the fiberglass and the ring will prevent the rubber boot from ever coming off.
•
Firmly tighten both stainless steel hose clamps, one over the EHT and the other over the EST.
Then test the connection by pulling and twisting it. There should be no slippage at the joints.
NOTE: You should re-tighten each clamp a second time (at least 30 minutes after the first time you
tightened them) before raising the antenna to the tower, to be sure that there has been no cold
flowing of the PVC material on the rubber boot.
