Technician exam question T9B08
Subelement T9, ANTENNAS AND FEED LINES· Group T9B
Which of the following is a source of loss in coaxial feed line?
- A.Water intrusion into coaxial connectors
- B.High SWR
- C.Multiple connectors in the line
- D.All these choices are correct (correct answer)
WhyWater intrusion into connectors, high SWR, and multiple connectors in the line are all sources of loss in coaxial feed line. Water getting into connectors, a high SWR reflecting power back and forth along the line, and simply having more connectors (each adding a small loss) can all contribute to loss in a coaxial feed line, so all three are correct, answer D. Picking only one of A, B, or C would ignore other genuine, independent sources of feed line loss.
