At what frequency is the insertion loss of a two-way feed-through tap measured?

The insertion loss of a two-way feed-through tap is specifically measured at 55.25 MHz because this frequency is significant in various telecommunications and broadcasting applications. This frequency is located within the range of standard cable television channels and is critical for ensuring that signals can be distributed effectively without significant loss. Insertion loss refers to the reduction in signal strength that occurs when signal is split and transmitted through different paths, so accurate measurement at this frequency assures that the performance of the tap aligns with industry standards.

Other frequencies listed may not align with standard practices for measuring insertion loss in this context or may apply to different technologies or applications. The selected frequency ensures that the characteristics of the tap can be evaluated and compared against acceptable performance thresholds within the relevant operational framework.
