As Cecil says, a wider than expected bandwidth in an antenna of
given
size, is an absolutely sure sign of greater loss somewhere in the
wideband antenna system.
________________

I don't know your definition of an "expected bandwidth," but for a
reality
check--many forms of panel antennas used in FM and TV broadcast
transmission
have 20% or better SWR bandwidth, and radiate nearly every watt that
can be
delivered by the feedline with almost NO "matching" losses. They
have been
in routine use for decades at master antenna transmit sites all over
the
world.

==================================

I've no reason to doubt it.

But this is a topic about the bandwidth of physically small HF
antennas.

And as usual, when the slightest difference of opinion occurs,
somebody invariably feels impelled to go off at a tangent and drag in
something they feel more at home with, such as VHF and UHF TV
transmitting antennas, and, very soon, if we are not careful,
distractions such as scattering parameters, reflected power, etc.
