Methods Applied and Interpretation of Parameters:
          Coordinate System: y—axis is in the direction of the dipole arms. z—axis is from the basis of the antenna
          (mounted on the table) towards its feed point between the two dipole arms. x—axis is normal to the other
          axes. In coincidence with the standards [1, 2], the measurement planes (probe sensor center) are
          selected to be at a distance of 10 mm above the top edge of the dipole arms.

          Measurement Conditions: Further details are available from the hardcopies at the end of the certificate.
          All figures stated in the certificate are valid at the frequency indicated. The forward powerto the dipole
          connector is set with a calibrated power meter connected and monitored with an auxiliary power meter
          connected to a directional coupler. While the dipole under test is connected, the forward power is
          adjusted to the same level.
          Antenna Positioning: The dipole is mounted on a HAC Test Arch phantom using the matching dipole
          positioner with the arms horizontal and the feeding cable coming from the floor. The measurements
          are performed in a shielded room with absorbers around the setup to reduce the reflections.
          It is verified before the mounting of the dipole under the Test Arch phantom, that its arms are perfectly in
          a line. It is installed on the HAC dipole positioner with its arms parallel below the dielectric reference
          wire and able to move elastically in vertical direction without changing its relative position to the top
          center of the Test Arch phantom. The vertical distance to the probe is adjusted after dipole mounting
          with a DASY4 Surface Check job. Before the measurement, the distance between phantom surface and
          probe tip is verified. The proper measurement distance is selected by choosing the matching section of
          the HAC Test Arch phantom with the proper device reference point (upper surface of the dipole) and the
          matching grid reference point (tip of the probe) considering the probe sensoroffset. The vertical
          distance to the probe is essential for the accuracy.
          Feed Point Impedance and Return Loss: These parameters are measured using a HP 8753E Vector
          Network Analyzer. The impedance is specified at the SMA connector of the dipole. The influence of
          reflections was eliminating by applying the averaging function while moving the dipole in the air, at least
          70cm away from any obstacles.
          E— field distribution: E field is measured in the x—y—plane with an isotropic ER3D—field probe with 100 mW
         forward power to the antenna feed point. In accordance with [1, 2], the scan area is 20mm wide, its
         length exceeds the dipole arm length (180 or 90mm). The sensor center is 10 mm (in z) above the top of
         the dipole arms. Two 3D maxima are available near the end of the dipole arms. Assuming the dipole
         arms are perfectly in one line, the average of these two maxima (in subgrid 2 and subgrid 8) is
         determined to compensate for any non—parallelity to the measurement plane as well as the sensor
         displacement. The E—field value stated as calibration value represents the maximum of the interpolated
         3D—E—field, 10mm above the dipole surface.
          H—field distribution: H—field is measured with an isotropic H—field probe with 100mW forward power to the
         antenna feed point, in the x—y—plane. The scan area and sensor distance is equivalent to the E—field
         scan. The maximum of the field is available at the center (subgrid 5) above the feed point. The H—field
         value stated as calibration value represents the maximum of the interpolated H—field, 10mm above the
         dipole surface at the feed point.

3.2 Antenna Design and Handling

The calibration dipole has a symmetric geometry with a built—in two stub matching network, which leads to the
enhanced bandwidth.
The dipole is built of standard semirigid coaxial cable. The internal matching line is open ended. The antenna is
therefore open for DC signals.
Do not apply force to dipole arms, as they are liable to bend. The soldered connections near the feedpoint may
be damaged. After excessive mechanical stress or overheating, check the impedance characteristics to ensure
that the internal matching network is not affected.

After long term use with 40W radiated power, only a slight warming of the dipole near the feedpoint can be
measured.
