•
Lay the element housing unit (EHU), Figure 1 - G, and element support tube extensions (EST)
Figure 1 - A,C flat on their sides. There will be a 3/4” diameter piece of plastic pipe protruding
out the end of the EST with a coupler attached to it (Figure 5).
•
Firmly glue in (using the PVC primer/glue supplied) the 89” section of 3/4” diameter plastic pipe
(Figure 1 - D), that also has a coupler attached to one end.
•
Next glue in the second section of 3/4” diameter plastic pipe (Figure 1 - B) with the inside
chamfered ends.
NOTE: If you need to take the antenna apart in the future you can cut the 3/4” diameter plastic pipe
(after homing the copper) a minimum of 1 in. above the coupler and when you are ready to
reinstall the plastic pipe glue in a new coupler.
•
Now install the two section of the EST extension tube (Figure 1 - A, C). The first section goes
firmly onto the EHT tube and the second EST goes on to the end of the first section. (Figure 7
and Figure 9 on next page)
Warning: Be certain that the metal coupler on the extension ESTs firmly bottom out.
