ARENTI SW-28HF Power Meter for RF Measurements
The ARENTI SW-28HF is a new 2-in-1 accessory designed for measuring voltage standing wave ratio and forward power. It covers a frequency range from 1.5 MHz to 60 MHz with a maximum power rating of 120 W. The meter targets radio operators and technicians who need portable RF diagnostics.
Accuracy and Display Limits Within the Specified
Accuracy is stated as better than five percent based on the detector diode fitting algorithm. The instrument operates only within the 1.5 MHz to 60 MHz band and up to 120 W, so measurements outside these limits are not supported. A buzzer sounds when the standing wave ratio exceeds 2.0. The built-in lithium battery provides more than 50 hours of continuous use.
Simple Connection Procedure With a Usage Caution
The meter features five selectable interface displays that switch with one click, plus normal and peak hold modes on an illuminated screen. Multi-function buttons control the unit and allow future expansion. The supplier notes that the device should be connected only during measurements and disconnected afterwards to reduce operational stress and prevent damage.

Questions about this item
Which version of the ARENTI SW-28HF should I choose for my radio setup?
The SW-28HF is a single model covering 1.5 to 60 MHz with 120 W power handling, so there are no alternate versions or capacities to select from.
What does the 120 W rating mean when I connect it to my transceiver?
It is the maximum forward power the meter can measure continuously; the buzzer sounds when VSWR exceeds 2.0, protecting the unit during real-world use.
What interface does the meter use and what does it limit in practice?
It connects in-line via standard RF connectors; the 1.5–60 MHz range and 120 W ceiling set the frequency and power limits for accurate VSWR and power readings.
