Do I have to use the provided antenna installed on the SuperSting™ to use the SSM App?

Short Answer: No, but connection may be unstable.

Long Answer: No, you do not have to use the provided antenna on the SuperSting™ to use the SSM App. However, not using the antenna will result in the Wi-Fi connection only being stable at a few meters away—as opposed to up to 100m* with the antenna.
