Folded dipoles and regular dipoles radiate the same. Your idea of
radiating
off the ends is wrong. Both types of dipoles radiate their maximum signal
at
right angles to the plane of the wire. That is if the wire (or tubing)
runs
north/south the maximum radiation with be east/west. This assumes the
dipole
is horizontal, if it's vertical then it radiates equally in all horizontal
directions. This is for a dipole in free space. Depending on the frequency
and the height of the antenna the pattern may change. Such as a dipole for
the 3.5-4Mhz ham band mounted 10m up, with radiate most of its signal
straight up.

Thanks John that was a great help.


I don't know what RSl broadcasting is here in the US so I can't
give anymore detailed answers.


RSL is a basiclly a legal tempoary radio station broadcasting on either
87.7MHz or 87.9MHz FM.
