I have seen a SWR curve much like that at one time, although it was nowhere that wide it covered a impossible bandwidth with peaks and dips under 3:1 and it was a I10-K base antenna, when I plotted the Curve I called Jay and asked what he thought about it, his first thought was bad Coax.
Soon after I replaced the old Coax with LRM-400 and magically the SWR plot became normal.
The thing is that the antenna worked just fine throughout the 10/11 meter band with no apparent problem.
Just my 2 cents worth.
