One of the best things you can do to prevent ESD failures is to develop a habit of discharging any cable before you mate it with any kind of equipment.? Cables can acquire a many-thousand volts charge by bending, handling or unrolling them, as well as by being attached to an ungrounded antenna, and hold it for a surprisingly long time.??
Simply shorting inner and outer conductors with the outer conductor of the mating connector is sufficient and will go a long way towards protecting your equipment.? Get into the habit of doing this EVERY time.
