What is, disconnecting the wire or leaving it in place?
Your comment can be taken both ways.

More importantly, if the "station ground" - the ground from the antenna entry
panel - is not bonded to the power entry ground, a lightning event can be
carried from the chassis of the power supply back through the electrical system
safety ground to the power entry *or vice versa* depending on the location of
the "strike".
This greatly increases the chances for damages to station equipment and all
other electronic equipment in the household in event of a lightning event.
