Return Loss: Positive or Negative? Both - Here's Why https://hubs.ly/Q04qzbCf0 Ever wondered why your analyzer shows a negative return loss, but the spec expects a positive value? You're not alone.

Understanding return loss can be confusing due to differing conventions. Learn how to interpret measurements and avoid costly mistakes in RF engineering.
