All begin reading the advice of a reseller on a Italian ham magazine, that
claim this (translated):

"The MFJ 1796 antenna only at XXX euro !!! 2,6,10,15,20,40 meters Superior
Half-Wave configuration !!"

Oh well, i'm really a rookie on antenna theory, but - thinking into
myself - someone at MFJ can please explain me what the hell make on this
antenna to shrink an half wave antenna on 40 meters into a stick shorter
than quarter wave??


It is easy to put anyting on paper. Antenna gain advertisement was so bad
that many years ago the ARRL would not let anyone put gain numbers in their
advertisements.
Most things made by MFJ are not very well thought of in the US.
