The Emit Standup loop is connected to the Emit Time Station ETS, and is used in events where participants use emiTag, and it is not possible to place an eLine loop across the trail / track. Standup loop is placed next to the trail and has a range of about 7-8 meters. When the emiTags register the loop, sending data to the ETS is activated. Used for intermediate time and gives an accuracy of about 1/10 sec.
The standup loop comes with a "built-in" antenna for receiving data from the emiTag chips, so you do not need an external Yagi antenna.
