Methods Applied and Interpretation of Paramieters:
   * Measurement Conditions: Further details are available from the Validation Report at the end
          of the certificate. All figures stated in the certificate are valid at the frequency indicated.
    s     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.
     e    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.
      e   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%.

General Antenna Parameters and Design

      Electrical Delay (one direction)                                                  1.143 ns


After long term use with 100W radiated power, only a slight warming of the dipole near the feedpoint 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 dipote length is still
according to the Standard.
No excessive force must be applied to the dipole arms, because they might bend or the soldered connections near the
feedpoint may be damaged.
