Actually it is on the side of the building even with the roof line.
The cable from the GPS runs through around 20 feet or more of conduit to the clock controller not counting the three feet of soffit that extends from the side of the building to the edge of the roof.
Point is it is very difficult to install and not that much easier to remove. So no, there is no good or quick way to get it on or off.
Once it is mounted it would take a good while to get it out and even more to re-install it.
Actually much more trouble than it would be worth.
If it came down to that it would be easier just to synchronize the clock to our cell phone once a month.
The only other alternative is a reliable way of providing it a backup power source in the event of a hurricane and extended blackout.
