Sorry Marconi, I didn't mean to suggest this change in impedance was a bad thing. Just that the matching network on the 5/8 would have to be changed to accommodate the new lower impedance. It seems you may have swept the radials up too high in an attempt to match the impedance? Forget the impedance and try reducing the upward angle on the radials to around 45 degrees. I think you may find the 40 degree lobe is still reduced but it may also make a slight increase in gain if it behaves like the Sigma.
