Nonsense!  Some 30+ years ago W2PV showed that a monobander was a
monobander no matter what the element spacing as long as the elements
are properly tuned for their place in the array.  Gain is a product
of boom length as long as there are "enough" elements for the length.

Tapered spacing only effects the bandwidth and feed impedance of the
antenna and with a SteppIR bandwidth has no meaning since the antenna
is constantly retuned for the operating frequency.

SteppIR is a tunable "monobander" with a fixed length boom - other
than the optional fixed length elements for six meters, a SteppIR
has no traps or parasitic elements whose sole purpose is to allow
operation on more than one frequency at a time.
