•
Match antenna polarity.
The figure below shows a vertically polarized panel and omni:
•
Test both vertical and horizontal polarity
. As with panel-to–panel systems, horizontal
polarization may improve performance in some systems, The figure below shows a
horizontally polarized panel and omni:
•
Test different power levels.
Lower power levels may actually improve reception due to a
reduction in multipath interference.
