SWR measured on a MiniVNA with Hexbeam @12m above ground

SWR is under 2:1 on all bands first RED line is 1:5

20 Metres 14.00 to 14.350 

17 Metres 18.068 to 18.168

15 Metres 21.00 to 21.450

12 Metres 24.890 to 24.990

10 Metres 28.000 to 29.700

6 Metres 50.000 to 52.000

I have kept the resonant frequency slightly high to compensate for the shift in frequency caused by rain fall. This also helps keep the SWR low well into the CW and Data portion of the bands.
