I`ve already defended the radial mode helix, but think of almost any
simple antenna. Doesn`t the half-wave dipole dradiate principally at
right angles to its axis?

Best regards, Richard Harrison, KB5WZI


It doesw radiate at right angles of the axis but for maximumum
radiation of a particular TYPE then the resultant maximum radiation
vector is between ten and fifteen degrees from the ninety angle.
The total radiation is the same at right angles as to that when tilted
10 degrees or more from that angle.
If you play with the angles on any computor program including EZNEC
I suppose, using a wavelength radiator, this is readily seen
Remember, do not stray from the term "RESULTANT VECTOR" which
is the subject of discussion.End of discussion
