ATTACHMENT
When the antenna is in its final location, apply
some
of
the
silicone on
the outer
threads of the
connector
on the UltraMatch.
SILICONE
SHOULD NOT BESPREADON THE
CENTER PIN!
Attach
your
feedline connector to the UltraMatch. Tape
your
feedline down the boom and mast as shown in figure l. lt's a
good
idea to
provide
a drip
loop in
the
coax as shown to help
protect
the connector from water
damage. Some recommended
stack-
ing arrangements
are shown on figure J.
