Which of the following is an advantage of waveguide as a transmission line?
- AHeavy and difficult to install
- BLow loss
- CFrequency sensitive based on dimensions
- DExpensive
Correct answer: B — Low loss. From the official ISED question bank, verified word for word.
Why
Waveguide acts like a hollow metal pipe that carries high-frequency radio waves with very little energy turning into heat, which is why low loss is its main benefit. The full explanation — and one for every question — is in Pro.
