Please be aware that the C4V has a different horizontal beamwidth pattern than the C2V. It
might be a little more difficult to find an aim for the C4V that will cover 327 to 22 degrees.
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.
