What is the best place to position the Sentinel repeller?
Where should I install the repeller?

Importantly, the ultrasonic repeller has to be pointing at the area to want to protect. Any obstacles in the way will create a shadow (think of a torch beam). Often the mounting position is a compromise between what would be ideal and what is possible. The ultrasonic deterrent is mains powered and is supplied with 10 meters of low voltage cable that runs from the standard 13 amp UK plug to the repeller housing. If you want to protect your garden at ground level, ideally you would position the device a few feet off the ground pointing slightly downwards.
