18.7 “Optimal Antenna Selection” test
The antenna test is used to verify the suitability of the selected antenna. Because
of reflections, the network scan can show similar results for different antennas.
However, during transmission of data to an access point, the differences between
antennas become significant. This test is worth running if more than one antenna
shows similar results.
