G9A08:If the SWR on an antenna feed line is 5:1, and a matching network at the transmitter end of the feed line is adjusted to present a 1:1 SWR to the transmitter, what is the resulting SWR on the feed line?

If the SWR on an antenna feed line is 5:1, and a matching network at the transmitter end of the feed line is adjusted to present a 1:1 SWR to the transmitter, what is the resulting SWR on the feed line?

Direct answer summary (2023-2027 NCVEC pool)

The official correct answer for G9A08 is 5:1.

The key fact is 5:1. Match that fact to the exact condition in the question; the other choices describe a different rule, band, component, or operating situation.
