To test for the best coverage use a test beacon at regular distances
away from the receiving antenna until the alarm no longer activates, this will
indicate the maximum range of the system. To find out if you have any radio
blind spots move around your area and repeat the above test process. To
overcome radio blind spots increase the height of the external antenna or
reposition the antenna.
