All figures stated in the certificate are valid at the frequency indicated. «_ Antenna Parameters with TSL: The dipole is mounted with the spacer to position its feed point exactly below the center marking of the flat phantom section, with the arms oriented parallel to the body axis. * Feed Point Impedance and Return Loss: These parameters are measured with the dipole positioned under the liquid filled phantom. The impedance stated is transformed from the measurement at the SMA connector to the feed point. The Return Loss ensures low reflected power. No uncertainty required. * Electrical Delay: One—way delay between the SMA connector and the antenna feed point. No uncertainty required. «_ SAR measured: SAR measured at the stated antenna input power. «_ SAR normalized: SAR as measured, normalized to an input power of 1 W at the antenna connector. * SAR for nominal TSL parameters: The measured TSL parameters are used to calculate the nominal SAR result. The reported uncertainty of measurement is stated as the standard uncertainty of Measurement multiplied by the coverage factor k=2, which for a normal distribution Corresponds to a coverage probability of approximately 95%.

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 armsin 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 accordingto the Standard. No excessive force must be applied to the dipole arms, because they might bend or the soldered connections nearthe feedpoint may be damaged.
