If anything gets the blame for poor transmit performance in CB radio, it is the SWR. But what does the standing wave ratio really mean, how do you measure it, and does a good SWR solve everything? Part three of our radio series.
You now know where the high-frequency signal comes from and how it reaches the antenna. Part two follows the signal into the radiator: the dipole, the three common antenna types and the right mounting spot.
Why does an antenna produce signals when an alternating voltage is applied, and how is speech carried on that? Welcome to CB radio, which still matters for travel and off-road driving. In this series we walk you through the tech.
