Annual validation for test lab. Appendix Annual validation for Test Lab. General calibration information Date 2019.10.22 Test Laboratory ShenZhen Morlab Communications Technology Co., Ltd. Antenna serial No. D2450V2-SN:997 Antenna Parameters with Head TSL Impedance, transformed to feed point 47.04Ω-2.73jΩ Return Loss -34.36dB General Antenna Parameters and Design Electrical Delay (one direction) 1.276 ns After long term use with 100W radiated power，only a slight warming of the dipole near the feed point can be measured The dipole is made of standard semirigid coaxial cable. The center conductor of the feeding line is directly connected to the second arm of the dipole. The antenna is therefore short-circuited for DC-signals. On some of the dipoles, small end caps are added to the dipole arms in order to improve matching when loaded according to the position as explained in the "Measurement Conditions" paragraph. The SAR data are not affected by this change. The overall dipole length is still according to the Standard No excessive force must be applied to the dipole arm， because they might bend or the soldered connections near the feed point may be damaged .
