Fast Made a Half- Wave
Antenna for 80 Meters |
 |
|
|
L2 is placed
at the bottom of L1. L2 contains 4 turns of copper wire in diameter
of 1.5 millimeters (# 14 AWG), length
of winding is 10 millimeters. Ends of L2 are directly soldered
to RF- socket. Neon Bulb is attached by a piece of Scotch to the
bottle. Antenna is tuned by max glow of the Neon Bulb. The antenna
worked very effectively when the upper end of the antenna was
placed at height of five or more meters above the ground. I did
not use an end antenna insulator. A long synthetic rope was attached
to the upper end of the antenna. |
The counterpoise of
the antenna was located on the ground surface. Between the "bottle"
ATU and a transceiver could be placed coaxial cable with any reasonable
length. Figure
3 shows the antenna at field operation. Of course,
it is possible to use the antenna for stationary work from a ham
shack. The antenna
works very well and I recommend try it! 73/72! |
