It seems to me that with an antenna switch that doesn't short the unselected antennas by default, like the DX Engineering RR8A-HP remote antenna switch, it might be advisable to either set the switch up to short the unselected antennas or add a resistor across them individually. Otherwise when an antenna carrying a significant static charge is switched to a radio, the charge might overwhelming the radio's protective resistors.
Whether dammage would occur depends on the inductance between the antenna and the radio's sensitive components. The natural inductance of the feed line wiring will broaden the electrical pulse and give the radio's resistors more time to bleed off the charge. I have no idea if typical feed lines have enough inductance to protect a radio in these circumstances.
