1) Take a careful set of SWR and if possible front to back measurements
before starting .
2) If after installation, the original measurements on the C4 are degraded
you can turn the WARC 7 90 degrees which would significantly reduce it's
coupling to the C4.
3) Or proceed directly to step 2.
I have a C3S which has much of the same design at its heart as the C4. Even
though it is advertised as a 12 and 17 antenna (with a tuner). My
experience on 17 is that it performs only marginally better than my B'nut
vertical. On 12M the B'nut consistently out performs it by 2 S units! So
the WARC7 is not redundant at all.
