FCC Technician Exam Question Of The Day (T7C04)

Q) What reading on an SWR meter indicates a perfect impedance match between the antenna and the feedline?

A) 1 to 1

NJ2X Notes:
A one-to-one, 1-to-1, or 1:1 standing wave ratio (SWR) indicates a perfect impedance match between the antenna and feedline.  It also indicates that no RF is being reflected back toward the transmitter (not a good thing).  Yes, RF does travel in both directions through coaxial cable.
