1. Carefully inspect shipping container for signs of damage. If the shipping container is damaged, do not unpack the unit. Immediately notify the shipping carrier and Bird Technologies. If the shipping container is not damaged, unpack the unit. Save shipping materials for repackaging. - Page 13 Installation Reflected power and VSWR measurements provide indications of the impedance match of the transmitters (radios) with the antenna. Antenna damage or other degradation can cause an increase in reflected power and a higher VSWR, changes in forward or reflected power levels as measured at the Multi-Channel Power Meter should be investigated.
