What about the VHF
antenna is still in the near-field of the VHF antenna, and so sill be exposed to somewhat high levels of RF. But the frequencies are again so far removed that I doubt there will be an issue.
I am assuming that your WiFi
antenna is actually a full WiFi transceiver, with ethernet providing the data and power. Even in this case the electronics
should be shielded enough to eliminate any problems. You may need to put a ferrite choke on the ethernet cable, but I doubt it.
Even though there is the mast
between the two antennas, the VHF antenna will still "see" the close-by WiFi antenna (The VHF wavelengths are much longer than the mast diameter), but I doubt that there will be any significant interaction with respect to antenna tuning or interference
