Changing Antenna Polarization (Andrew Only)
Adjusting polarization depends on the antenna manufacturer and model. As a reference, the following
example is shown for the Andrew ValuLine series. The steps involved in changing polarization with other
antenna will be different. Please consult antenna documentation for details.
Loosen the screws using the Allen wrench supplied (Figure 5-8). You only need to make the
structure loosened enough to loosen the plate (Figure 5-9) and rotate the waveguide.
Pull up the loosened plate and rotate the cylindrical antenna waveguide (Figure 5-10).
When you have made a 90 degree rotation, alignment pins on the bottom side of the plate will
click in and settle back into the holes. Make sure that the plate is fixed in its place.
Tighten the screws to secure the plate and waveguide for the final position shown in Figure 5-11.
Figure 5-8: Loosening of the bolts. The current antenna position is vertical polarization.
