What component improves the ability to hear received signals?

• A. Tower Mounted Amplifier (TMA)
• B. Grounding Wire
• C. Coaxial Stub
• D. Harmonic Filter

Answer: (A)

Tower Mounted Amplifier boosts the strength of incoming signals right at the antenna, before they travel down the feedline. By increasing the signal level at the source, it improves the signal-to-noise ratio and makes weak signals easier to hear at the receiver, especially when distances are long or conditions are marginal. Grounding wire protects equipment but doesn’t improve reception. A coaxial stub is used mainly for impedance/ tuning at specific frequencies, not for overall signal boost. A harmonic filter removes unwanted harmonics rather than increasing the strength of the desired signal.
