Sleeve vertical dipoles are quite common, but I don't get the
description of two vertical side elements...??


Actually, one doesn't even need two side elements. One
element will function with the outside braid to turn
the decoupling section into a balanced 1/4WL stub which
functions essentially the same as the unbalanced 1/4WL
decoupling sleeve. Such is illustrated on page 26-9,
Fig 11, of my 15th edition of The ARRL Antenna Book.
