Dani, ZS3D and ZS6CCY were 59 on the Mod Bob tuned for 40M, so I have just confirmed that its as good or better than the broadside direction on the DX Engineering DV-40-P. I broke through small pileups and was first in in both cases.
What was especially cool was that this was during a major solar storm – with a radio blackout in progress. I am very confident that taking down the 40M array won’t affect me working 3Y0Z at all. SO – in the next couple weeks, my latest antenna “escapade” will be done.
