Technique for terminating an antenna
aerial wire to a strain insulator with a tail for connecting to the
feed line. The technique while more laborious than swage crimps and
similar methods is mechanically superior as there are no points of fatigue
failure and electrically there are no connections. This technique is
most suited to heavier antenna wire of 4mm2, 7 strand or greater.
Photo#1. Feed antenna wire through
the strain insulator with sufficient tail length to reach the feed line
Photo#2. Form the wire so that the
main antenna wire lays against the tail and feed the tie wire
through. The tie wire will need to be about 2mtr long subject to the
antenna wire size, The tie wire will located in the insulator so
that about 300mm is presented on the tail side.
Photo#3. The sorter tail side of the
tie wire is laid along the antenna wire and tail with the longer
side wound on tightly binding the antenna wire, tail and sort side
of the tie wire together.
Photo#4. Rap for at least 10 turns
and bend the main antenna wire away as shown above.
Photo#5. Continue tightly raping
along the tail and sort tie for at least 10 turns.
Photo#6. Form the main antenna wire
and tail together and continue tightly raping for at least 10 turns.
Photo#7. Bend the tail and short tie
wire away as shown above and continue tightly raping for at least 10
Photo#8. Rap the short end of the tie
along the tail for approximately 3 to 5 turns as shown above.
