Larry,
Is it a 'valid' antenna? Ah, yes, with several 'buts' that
'add to' / 'subtract from' that 'validity'. The 'biggy' questions
are what length and what frequency of use? Those will determine
the input impedance of the thing, and who says that a 9:1 is
going to be the 'right' impedance transormation ratio? That
9:1 thingy is basically taking the place of a tuner, which would
make the thing a much more 'valid' multiband antenna, but not
necessarily a very broadbanded one.
So while there is some validity, I don't think I'd say it was
totally valid, broadbanded, or multibanded. Not bad advertising
though...
