Carefully separate the two halves of the antenna without cutting any plastic cable
ties that hold the antenna wires in place in the packaging.

Ensure that the wires connecting the balun to the centre spreaders are above the
main antenna wires.

Attaching the antenna to the stub masts
Figure 4: Stub mast and antenna
To attach the antenna to the stub masts:
1
Pass a 3 m halyard through the insulator at each end of the antenna, then tie it off on
itself.
1
Fit a wire rope grip to secure each knot.
1
Temporarily tie off the short halyards to the stub masts.
1
Erect the stub masts.
CAUTION
Take care not to tangle the wires. Do not cut any of the wires.
NOTE
Each stub mast should be equipped with a suitable eyebolt or similar
fixing for tensioning and tying off the short 3 m halyards.
NOTE
Ensure the knots are tight and will not come undone under tension.
