What is a benefit of low SWR?
Reduced television interference
Incorrect. Reduced television interference is not directly associated with SWR; it is more commonly influenced by proper filtering and shielding practices.
Reduced signal loss
Reduced signal loss is the correct answer because a low SWR indicates efficient power transfer with minimal reflected power, thus reducing signal loss.
Less antenna wear
Incorrect. Less antenna wear is not directly related to SWR; while excessive reflected power can eventually damage components, it is not termed as ‘wear’.
All these choices are correct
Incorrect. Not all these choices are correct; the primary benefit of low SWR is the reduced signal loss due to efficient power transfer.
Explanation
Standing wave ratio (SWR) measures the efficiency of power transfer between the transmitter and the antenna in a radio communication system. A low SWR indicates that the system is matched well, meaning that most of the power emitted by the transmitter is being radiated by the antenna rather than being reflected back into the system. This is crucial because reflected power can lead to signal loss, reduced transmission efficiency, and potential damage to the transmitter. By ensuring a low SWR, you enhance the overall performance and reliability of your radio communication system.
