EXAMPLE: 16 RADIAL WIRES WILL BE PREPARED IN GROUPS OF 2 (or 4).
Cut 2 (or 4) equal length radial wires, each 20 to 40m long. (2 wires shown)
Remove 2cm (
¾
”
) of insulation from one end of each wire.
Splice the wires together by twisting them as tight as you can.
Trim the splice to 1.5cm with wire cutters.
DO NOT SOLDER BEFORE CRIMPING.
Cut a piece of heat-shrink tubing (9/3mm) 2cm (
¾
”
) long and slide it over
the splice and 2 (or 4) wires.
Insert the splice into a M6 cable solder lug and crimp the lug
using a crimp tool or pliers.
Now solder the wires inside of the solder lug.
Weather proof the 2 (or 4) wires at the lug with 2cm of heat-shrink tubing, and seal the
other
end with “liquid electrical
tape”, or similar.
You may also use y
our XYL’s nail
polish for this. If using nail polish, apply 2 or 3 coats, allowing to dry between coats.
This completes the preparation of the first 2 (or 4) ground-mounted radials.
Now prepare 7 more sets of 2-radials (or 3 more sets of 4 radials) exactly as you have
done above.
This completes the preparation of the 16 ground-mounted radials.

Preparing the Top-Hats
For space reasons, it is probably easier to prepare the top hat wires in the field.
You will need to solder at least one connection in the field. This
will require a soldering iron with at least 60w.
You will need 4 small weights to attach to the ends of the top-
hat lines to keep them under tension during the installation of
the antenna. W
e recommend large “lead
sinkers”
like fishermen
use to weight their fishing lines. A 4-oz. to 5-oz. (112 to 140 gr.)
sinker is heavy enough. You may substitute with something
else, but
do not use heavier weights
.
