The C2V claims 70 degrees

The C4V has a more narrow main lobe but 2 secondary lobes to make it a little wider

page one shows a narrower (43) main lobe, but page 2 claims wide (70) coverage
The peculiar pattern with the two notches (nulls) that changes with frequency is the result of horizontal stacking. This pattern that has nulls is used in the Two-Antenna Trick on hdtvprimer.com with the phase reversed.
You can also see it in the pattern of the DB8e, which is two 4-bay antennas side-by-side.

Thanks so much for your help rabbit73, being a layman I was affected by the advertising. I am definitely going to take your advice and get the c2v, it's cheaper too! I really have much to learn. Thanks again.
