In very rough terms, the DBGH ought to have about 6 dB more gain than a 4- bay bowtie.
I would not have expected WCAX to be that difficult to receive with a 4-bay bowtie in the attic. What dimensions did you use for your 4-bay antenna? Do you have a screen behind your antenna? I wonder if your current antenna could be tweaked to give you better performance on channel 22.
Another possibility is that there is something in the building materials of your house (e.g., wire mesh, foil-backed insulation, ducts, metal bracing, etc.) that is interfering with your reception.
