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.

Garmin's new dezl LGV series brings high-resolution displays, satellite images, truck-specific routing and weather warnings, plus community info on parking and loading ramps.
Locus Map, for years the benchmark off-road navigation app, was Android-only. Now Locus Map Lite has arrived in the Apple App Store, still limited but a real start.
Satellite internet is one way to get fast internet on the road, and by now Starlink is a real alternative to local SIM cards or slow wifi. But how well does it actually work in practice for travellers? We asked two who use it on the road and at sea.
Low emission zones and driving bans affect older vehicles and diesels across Europe, so off-road travellers too. Our country-by-country overview and how to plan your route around them.
IGN Mapas de España is a free OruxMaps-based app with hiking-map detail, offline maps and track support, useful for off-road tours in Spain.
Locus Map now offers its own global satellite and aerial imagery (LoSat) from HERE, Maxar and Eurographics, available with the Premium Gold subscription.
