The SWR increase is a good thing as it shows deminishing ground losses exposing the true mismatch of the 50 ohm coax to the impedance of the vertical. So with a limited radial field, the mesh seemed to help....
My first Inv L back in 1998 with one radial was a flat 1:1 match until W0YG explained to be what was going on. By the time I added 60 1/4 wave radials, I was at 4:1 at resonance and used an UnUn to match the coax to the vertical for a 1.2:1 match. Still use the UnUn with my MA160V and MA80/40V .....

It might not add much improvement to a very extensive 160 radial field however. Expect your SWR to increase somewhat.
