We are creating a vehicle as sort of a communications center on wheels. It has satellite, HF, VHF, UHF, and Amateur radios on board, and lots of antennas on top. I have a mast for the Wi-Fi bits, and I am wondering whether mounting outdoor omni 2.4Ghz and 5GHz antennas within 4" (horizontally) of each at the top of the mast is acceptable? I know that you should not mount two 2.4GHz antennas this closely when they are controlled by two different APs, even on different channels, but wasn't sure about antennas from different frequencies (controlled by the same AP).
Also - these antennas are within 4 to 8 feet of the antennas for all the equipment listed above. What sort of problems are we likely to experience?
Thanks in advance...
