What happens to power lost in a feed line?
- A.It increases the SWR
- B.It is radiated as harmonics
- C.It is converted into heat (correct answer)
- D.It distorts the signal
WhyPower lost in a feed line is converted into heat. Power that's lost as a signal travels down a feed line is dissipated as heat in the line's conductors and dielectric, answer C. It doesn't directly raise SWR (A, that's a function of the impedance match, not line loss), it isn't radiated as harmonics (B), a feed line doesn't generate new frequencies, and simple resistive loss doesn't distort the signal's shape (D).
