I am not sure where you are getting your information that cutting the losses
in your 160 vertical from 60 - 37 Ohms will have no difference in
performance - technically or noticeably but its not correct.
Reducing ground losses is THE ISSUE on 160M. Calling a 1.2:1 SWR great and
not realizing what is being traded to get there, it really lacking of the
A 160M antenna should have the lowest possible losses for the site and then
the resulting SWR matched or tolerated. Not the other way around.

Theoretical impedance for a perfect 1/4 wave ground plane is 37 ohms. 60
ohms is great; 1.2:1 VSWR ? leave it alone, you will never notice any
difference if you try to improve it. It will change with rain, snow, etc
anyhow..73 Jay ny2ny"
