Not true, Bob. Don't confuse SWR bandwidth with how well the antenna
works. Study W2DU's excellent work on this, which is on his website.
Google to find it.
Both here in Santa Cruz and back in Chicago, I've quite successfully
used 80M dipoles cut for the low end of the band (typically around
3570 kHz) all the way up to the top of the phone band. All you need
is a decent tuner. I use the Ten Tec 229 and 238 (essentially the
same, different cosmetics), which are rated for legal power. The
antenna in Chicago was even narrower than a standard dipole because
it was shortened and used loading coils, but it worked fine too.
It helps, of course, to use bigger, high power coax if you're
running power. But I ran here in Santa Cruz for nearly a year with
RG59 into my high dipole, and it worked fine.
