Antenna InformaƟon Manufacturer Shenzhen Chenxing Electronic Technology Co., Ltd. Antenna Type Coil Antenna Model KFT-107 Antenna Part Number 107-27X8.1-0.06X65PX15TS-10uH-13mm-01 Antenna Frequency Range 100 ~ 200kHz Antenna Input Power LimitaƟon N/A Antenna Peak Gain N/A Antenna Dimension (LxHxW) 27 X 26 X 3.6 mm Antenna Photo Antenna Top View [With Ruler] Antenna BoƩom View [With Ruler] The subject device is equipped with a permanently attached and non-removable antenna. The antenna cannot be replaced or modified by the end user. Since the antenna is fixed and integral to the equipment, compliance with the antenna requirements is fully demonstrated through radiated emission measurements. Therefore, antenna gain information is not applicable, and the Radiated spurious emission test results included in test report are sufficient to show compliance.
