my SWR reading

As an example I have a ten metre dipole in my loft, some 25 feet
above ground. It resonates at 28.44 at the end of approx 10 metres
of 50 ohm coax, the SWR is 1.4:1 . The bandwidth at 2:1 is 28.25
-28.63. At 2.5:1 it is 28.160-28.760. This is before the ATU, after
the ATU the TX sees from 1:1 to 1.4:1 over the whole of ten metres.
You didn't mention the balun, it is significant.
