What areas of 10 meters will you be operating in mostly?
If it is CW you don’t need to do anything. If it is SSB and you are staying in the 28.300 to 28.500 voice section (tech license) the VSWR looks like it is getting better. (lower) If the SWR is 2:0 at 28.000 and 1:7 at 28.300 then it is likely going to be less (1:5) at 28.600.
can you tell us a little about your set up and deployment?
Antenna height and direction?
Any surroinding objests etc. All information helps.
but just looking at the numbers you have provided it looks good.
An SWR of 1:7.1 is plenty acceptable. Any SWR beolw 2:0.1 is acceptable to the radio.
