The SBA 9112 was designed because of the worldwide unavailability of omnidirectional or dipole-like broadband antennas operating above 3 GHz. In combination with the SBA 9113 a frequency range from 0.5 to 18 GHz can be covered with excellent antenna performance. Accepting some limitations (i.e. Antenna Factor and VSWR increase, symmetry reduction) the SBA 9112 can be used from 1 GHz on. The validation of test sites with commonly used Microwave antennas (e.g. Log.-Per. or Horn Antennas) leads to insufficient results, since these directive gain antennas with concentrated directional pattern do not take the test site characteristics into account.
- The SBA 9112 are compliant to CISPR16-1-4:2007-02 Ed. 2.0 for site validation above 1 GHz.
