## Summary description

Albrecht SWR30 is an HF measuring device designed to measure standing wave ratio (SWR) and relative RF power across 30–300 MHz. It provides frequency-specific SWR readings for antenna tuning, installation and troubleshooting of VHF/UHF equipment. Compact and portable, it is suited for amateur radio operators, technicians and field use where antenna matching and signal quality checks are needed.

## Long description

The Albrecht SWR30 is a compact HF measuring device that measures standing wave ratio (SWR) and relative RF power across the 30–300 MHz frequency range. Designed for antenna tuning, installation and troubleshooting of VHF and UHF equipment, the unit delivers frequency-specific SWR readings to support accurate antenna matching and signal quality checks. Portable and straightforward to operate, it is intended for use by amateur radio operators, technicians and field engineers who require a reliable meter for on-site diagnostics.
Advantages
The device offers a broad coverage of 30–300 MHz, enabling measurements across common VHF and UHF bands. Its compact, lightweight design supports portable field use and easy integration into workshop toolkits. Readouts provide both SWR and relative RF power information, allowing users to assess antenna matching and transmission efficiency in a single instrument. The straightforward operation reduces setup time and simplifies routine checks and troubleshooting.
Suitable for
 Amateur radio antenna tuning and alignment
 Field testing of VHF/UHF communication systems
 Installation and verification of antennas for base stations and mobile units
 Troubleshooting mismatches and feedline faults
Key specifications
 Frequency range: 30–300 MHz
 Measured parameters: standing wave ratio (SWR) and relative RF power
 Display: analog/dedicated meter (visual SWR and power indication)
 Form factor: compact, portable handheld unit
 Typical use environment: workshop and field operations
How to use
Connect the SWR30 between the transmitter (or signal source) and the antenna feedline using the appropriate coaxial connectors, observing correct polarity and securing connections. Power on the transmitter at a low output level and key the transmitter while observing the meter. Tune the antenna or matching network and watch the SWR indication; adjust elements or matching components until the lowest achievable SWR is obtained across the desired frequency. Monitor relative RF power readings to confirm the transmitter is delivering expected forward power and that losses are not excessive.
Usage recommendations
Use low transmitter power during initial measurements to protect the meter and your equipment; make incremental adjustments and re-check SWR across the intended frequency range. For consistent results, perform measurements with the antenna installed in its normal operating position and avoid touching radiating elements while measuring. If high SWR persists after tuning, inspect feedline, connectors and antenna for damage or corrosion.
