I'm the worlds worst when it comes to disconnecting antennas. I know better, yet unless I hear nearby thunder, I don't unhook antennas. However, If I do happen to unhook an antenna, I ground the tip against something before I hook it back up to a radio. I have actually seen the spark jump to ground when I ground out a PL259 before reconnecting it. Don't do as I do, because I'm an idiot. Disconnect those antennas and ground them before reattaching them. Even just a strong wind can charge up an antenna.
