Al l figures stated in the certificate are va lid at the frequency indicated. Antenna Parameters with TSL: The dipole is mounted with the spacer to position its feed point exact-y below the center marking of the flat phantom section, with the arms oriented paral lel to the body axis.. Feed Point Impedance and Return Loss: These parameters are measured with the d ipole positioned under the liquid fil led 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 uncer taint y r equir ed. SAR measured: SAR measured at the stated antenna input power. SAR normalized: SAR as measured, norma l ized to an input power of 1 W at the antenna connector.. SAR for nominal TSL parameters: The measured TSL parameters are used to ca cu late the nominal SAR resu lt.

The dipole is made of standard semirigid coaxial cable. The center conductor of the feed ing line is directly connected to the second arm of the d ipole. The antenna is therefore short-circuited for DC-signals. On some of the dipoles, small end caps are added to the d ipole 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 excess ive force must be applied to the d ipole arms, because they might bend or the soldered connections near the feedpoint may be damaged.
