Step 4
Install the four Dipole Elements
Step 3: With an adjustable wrench, continue to rotate the cam element past the 30 degree point until the
wrench flats are parallel with the boom. At this point the two elements will be firmly locked into place.
When installing the two reflector elements, you will need to work the elements past the coax leadwire
inside the boom. The leadwire is routed in one corner of the boom. Insert the reflector elements first thru
the hole in the boom opposite of the leadwire. This will provide leverage while working the element past
the leadwire into the opposite hole. After installing the director and reflector element pairs, make certain
the wrench flats of all 4 cam elements are parallel to the boom.
Step 4: Install the four dipole elements. The dipole elements are 7" long and have a threaded stud on one
end. Screw the threaded studs into the boom and tighten lightly with a pair of pliers. Do not over
tighten. Over tightening may strip out the threads in the plastic insulator inside the boom.
