Antenna gain question

We have a 1242 AP and an ANT2506 external antenna. From what I've read I want to use a gain value of 10 for this antenna. However, there will be a 50 ft cable (AIR-CAB050LL) between antenna and access point. Do we need to adjust the gain setting for the cable?

Cisco uses LMR-400-DB for <50'

Thanks,
