Resolution
Wireless antennas can be painted as long as it does not cause any Radio Frequency (RF) propagation problems.
As long as you do not use a metallic, lead-based or graphite-based paint, you should not have problems. However, Cisco does not recommend painting the wireless antennas, since any alteration to the equipment may invalidate the warranty.
