Warning: Make sure to remove the black rubber plug from the base section of each of the telescop-
ing element support tubes (poles). This is a shipping plug for handling convenience and
will seriously damage the copper-beryllium strips and drive mechanisms if not removed.
Check all four sections of each pole for packing popcorn or any other foreign object that
could interfere with the copper tape movement.
There are foam plugs glued in the small end of each of the dark green telescoping
poles. These plugs allow the poles to breathe preventing the buildup of condensation
inside. Do NOT remove, block, cover, plug, cap or in any way inhibit air flow
through this foam plug filter.
Note: The telescoping element support tubes will not all be the same length, this is not a problem as
long as they are a minimum of 17’ 8”. They are interchangeable and can be used in any ele-
ment position.
Next wrap each joint on the fiberglass poles with the all weather electrical tape, see Figure 9. Each
joint should have at least the full width of the tape on both sides of the joint. Use common sense on the
amount of tape or you will not have enough of the silicon tape used later to cover the electrical tape.
Exception: On joints with reinforcing rings, the tape must continue further so it extends a minimum
of 3/4” beyond the metal ring and onto the fiberglass pole.
Apply one complete wrap of electrical tape around the fiberglass tube as you begin, and then work
your way across the joint and back using half overlap wraps, so that the entire area is seamlessly cov-
ered. Carefully stretch and smooth the tape with your finger as you apply, and especially when you
change directions - this will help avoid ripples and have the tape lie as smoothly as possible. At the
end of the run, cut the tape with a knife or scissors and press the end onto the pole. Then run your hand
over the tape a couple of times to firm up the bonding.
