AI summary

Techniques for configuring a repeater are disclosed. An independent oscillation reduction factor for reducing oscillation in the repeater can be determined when an overload protection is disabled at the repeater. The oscillation can be caused by feedback of one or more signals between a donor port and a server port of the repeater. The independent oscillation reduction factor can be indicated for use in determining an antenna installation location or orientation.
