Yes, the issue would be pickup on the feedline. The mechanism would be conversion of common mode current to a differential voltage on the coax due to a poor quality shield on the 2.4 GHz feedline. Like Dave, I would not expect a problem if you're using decent coax on that antenna (and you won't have much 2.4 GHz signal if you don't).
