5.15 HOIST THE BALUN
Fasten 12-inch rope loop of Weak Link to mast carrying handle. Attach balun to fixed hook of halyard
and hoist carefully and slowly. Use the coaxial cable to guide the balun. Tie a noose in the down line of
halyard so that the second Weak Link snap hook just reaches it. Snap Weak Link to the noose. Tie
the up line to the mast handle so that there is a slack loop of about 5 feet below the Weak Link.
During hoisting of the balun, the second person will guide the antenna elements and balun with the
coaxial cable.
Hoist the balun, coax, and wires, slowly, ensuring that nothing is caught while performing hoisting
operations on the balun.
Weak Link will snap at about 100 lbs (heavy ice/wind) causing a drop of balun/antenna elements of
about 5 feet. Weak Link designed to provide two uses. Now you are ready to tension the wires, using a
mirror image technique.
NOTE
In the following steps, it is not necessary, nor is it
required that the antenna elements be stretched tight.
The normal tension on the elements is about 10 - 20
lbs of tension. Some sag in the elements is desired.
Each individual should walk out to the stake at the #2 point (stake/rope/multi connector) and while
walking slowly backwards and away from each other, pull the center (#1 - 2) wire snug. Drive in the
stake (the one with the multi connector and rope tensioner). Each individual should move to a
diagonally opposite outer wire. There should already be a stake attached to the antenna element wire
there. Pick the stake up, pull against each other and away from the center stake you just drove in.
Positioning for the corner stake will become obvious, as far away from the mast and from the center
stake as you can comfortably tension it (remember, 10 - 20 lbs of tension).
