[Antennas] Simple Dipole Question

[Bob Wilder]

Of course you fed this antenna to an antenna tuner....Your actual antenna=
 will
appear as a dipole cut for about 4.3 MHz...that is about 116 feet each side=
=20
of center.
This comes from the 32.9 feet half wave dipole for 14.2 MHz (16.45 feet=20
each side of
center)with 100 feed added to each side of the dipole down to the 1:1 Balun.
If you use an antenna tuner this antenna should work well from 80 thru 10=20
meters...
BUT and antenna tuner is necessary.
