Question
What reading on an SWR meter indicates a perfect impedance match between the antenna and the feed line?
Answer Options
- A) 50:50
- B) Zero
- C) 1:1
- D) Full Scale
Correct Answer: C
Explanation
The Standing Wave Ratio (SWR) is a measure of how well the antenna (the load) is matched to the transmission line (T9B12). A perfect impedance match occurs when the load impedance perfectly matches the characteristic impedance of the feed line (usually 50\text{ Ohms}). At this point, all the power is delivered forward, and zero power is reflected back.
The SWR meter reading that indicates this perfect match is 1:1 (read as ‘one-to-one’). Any reading higher than 1:1 (e.g., 2:1 or 4:1) indicates a mismatch and reflected power (T7C06).
