Just as wide low SWR bandwidth on an antenna can be because of
significant loss resistance (as opposed to radiation resistance), a
wide bandwidth with a tuner may be an indication of high losses.
Although not necessarily in every case.
The best wideband load in my shack is a 50 ohm noninductive resistor. I
never have to adjust a tuner to get a good match for my transmitter on
any band. I have not made many QSOs with it though. Wide low SWR
bandwidth is not necessarily a good thing.
