SteppIR Antennas 40m - 30m Dipole Kit
12
Install Boom Counter-weights (4 Element ONLY):
On the 4 element antenna ONLY you will need to install a pair of counter-weights to the side
of the Director 2 element mounting bracket (Picture 3B) to balance the boom after the in-
stallation of the 40m - 30m dipole kit. These are powder coated steel bars weighing approxi-
mately a total of 8.2 pounds.
Locate: (Picture 3A)
•
Two steel bars 2-1/2” x 12” x 1/2” (counter-weights)
•
Two 1/4-20 x 3-3/4” bolts
•
Two 1/4-20 Nylok nuts
•
Eight 1/4” flat washers
Suggested Installation Steps (retrofit only):
•
On a retrofit installation you should not need to remove the element housing unit
(EHU) from the element mounting bracket but do be careful with the weight of
the EHU and the FTP’s attached when you remove the existing bolts.
•
Remove the first 1/4” bolt from the Director 2 element mounting bracket and in-
stall it back into its hole from the other side of the bracket. This will support the
bracket while you remove the second bolt.
•
Remove the second 1/4” bolts from the Director 2 element mounting bracket.
•
Put two 1\4” flat washers on each of the new 1/4-20 x 3-3/4” bolts.
•
Position the first counter-weight by lining up the holes so that the end of the
weight is even with the end of the element mounting bracket (Picture 3B) and in-
stall a new 1/4-20 x 3-3/4” bolts with the two flat washers through the empty
hole.
•
Now install the second new 1/4-20 x 3-3/4” bolts with the two flat washers
through the second hole pushing out the old bolt that you temporarily installed
from the other side.
•
Put the second counter-weight over the two new bolts sticking out.
•
Install two flat washers on each bolt and then the new Nylok nuts and tighten.
•
The end results should look like Picture 3B.
•
This completes the installation of the counter-weights.
