Most amateurs will tell you not to run them concurrent. The reason is, most installations do not have enough body mass under the antenna. Since the body if the other half of the antenna, the RF has to flow somewhere, and that's usually back over the control cables, coax, and in some case on the power cabling (parallel line currents).
If the antenna is mounted correctly, the amount of parallel line currents is practically nil, and so it doesn't matter how you route the wiring.
In my personal installation, the cabling is bundled and covered by one run of split loom. I have no RFI problems.
