What is the effect of transmission line loss on SWR measured at the input to the line?
Higher loss reduces SWR measured at the input to the line✓Respuesta correcta
Higher loss increases SWR measured at the input to the line
Higher loss increases the accuracy of SWR measured at the input to the line
Transmission line loss does not affect the SWR measurement
Explicación
Line attenuation acts on the forward wave once and on the reflected wave again on its way back, so the reflection reaching an instrument at the input is smaller than the one at the antenna. A very lossy line can read close to 1:1 even when the antenna is badly mismatched.
