A repeater serves a crucial role in extending the range of radio communications. Its primary function is to receive a radio signal and then re-transmit that signal at a higher power. This enhances the reach of the original transmission, allowing communication over greater distances and overcoming obstacles that might otherwise disrupt the signal.

In many radio communication systems, especially those used in tactical scenarios, maintaining clear and consistent communication is vital. Repeaters enable this by amplifying the signal, thus ensuring that users who are farther away from the original signal source can still receive clear transmissions. This capability is essential in environments where terrain and physical barriers can impede direct line-of-sight communication.

The other choices, while they represent different tasks associated with signal processing, do not accurately describe the primary function of a repeater. For instance, filtering unwanted signals pertains more to devices designed to refine and clarify signals rather than to enhance their power. Analyzing frequency is also a critical function in radio communications but is typically handled by other types of equipment, not repeaters. Recording signals for later playback is a separate function that primarily belongs to audio devices rather than repeaters, which are focused on live communication. Thus, the correct answer highlights the essential amplification role that repeaters play in radio signal transmission
