Tie a large knot about 10cm from its end and pull it tight, using a pliers to hold the short
end.
Pull the long end away from this insulator, pulling the knot inside th
e insulator’s slot.
When completed, each top-hat should look like this
o
This completes the first of 4 top-hat lines.
Repeat the procedure above for the next three top-hats:
Mount the insulators and PVDF line exactly the same as above.
This completes the preparation of all four top-hats.
TIP:
Temporarily tie the far end of the Monofil line to a small weight. We use heavy “lead
sinkers”
(140 gr. / (4 or 5 oz.) weights) sourced from a fisherma
n’s supply shop for this pu
rpose.
This should be just enough weight that it applies some tension to the line as you later begin to
raise the pole with the antenna.
Don’t use too much weight.
2.8.3 HIGH POWER OPTION (>1kW)
If you plan to run more than 1 kilowatt, you must take special precaution. You will need 3
insulators per Top-Hat Wire instead of 2 and you
must
use 1mm Kevlar rope between the
insulators instead of PVDF Monofil. Build it exactly as described in 2.8.2, but use 3 insulators
with 1mm Kevlar rope between them.
