5.3.1 The Bowline
The
Bowline makes a reasonably secure loop in the end of a piece of rope.
It does not slip or bind under load.
The Spiderbeam 160m Vertical Antenna uses the bowline to fasten the Kevlar
guy ropes to the optional guy belts. (see picture on the right)
.

5.3.2 The Overhand Knot
The Overhand Knot is the simplest of all knots. It makes a knot in
the end of a rope which can prevent fraying and can act as a simple
stopper knot. In the Spiderbeam 160 Vertical Antenna, it is used to
form the knots of the top-hat wires (see 2.8.1) and at the top of the
radiator wire (3.1.1) (see picture on the right).

5.3.2 The Sheet Bend
The Sheet Bend (or Becket Bend) joins two ropes that are of
unequal size
,
but also works well if the ropes are the same size.
Normally it will not slip, as long as both ropes are kept under
tension. Both ropes should be loose before you begin tying the
knot, and tensioned after the knot is tied.
IMPORTANT: If the ropes are of different sizes, the larger [blue]
rope must be used to form the loop on the left in this picture. The smaller [red] rope must
come from the right.
In the Spiderbeam 160m Vertical Antenna, it is used to join the Kevlar guy ropes to the short
6mm Polyester guy rope stubs (see 3.1.4.2). Leave both stubs long enough to attach wire-ties.
Hint:
after tying the knot, secure the tips of each short end of the rope to itself with a small
wire-tie. This will prevent the knot from coming undone when it is not under tension.
