OPEK SWR-3

Opek SWR-3 — SWR / Power / Antenna Field Strength Meter

The All-in-One RF Measurement Tool for Amateur Radio Operators

Take the guesswork out of antenna tuning with the Opek SWR-3 — the deluxe, multi-function meter built for hams who demand precision and versatility. Whether you're optimizing your antenna system, monitoring transmitter output, or measuring field strength in the field, the SWR-3 delivers reliable, accurate readings every time.

Using the bridge method to compare forward and reflected voltage, the SWR-3 accurately and quickly matches your antenna to your transmitter — making antenna optimization faster and more dependable than ever.

Key Features

The SWR-3 is the deluxe version of the SWR-2, offering all the same core functions with added capability, including a change-over switch for SWR and Watt measurement, a 10/100W power range switch, and a 5" antenna for Field Strength measurement.

Continuous in-circuit monitoring of transmitter output is possible by keeping the instrument in line at all times — no need to disconnect between transmissions.
