at 100M Pro Antenna Tuner Power Standing Wavemeter 1.8mhz to 30mhz

Our review of the at 100M Pro Antenna Tuner Power Standing Wavemeter examines a compact, battery powered SWR and power meter designed for portable radio operators and field use. The bottom line: this unit is for amateur radio operators and field technicians who need a small, all-in-one tuner and standing wave monitor that works across 1.8MHz to 30MHz without extra data cables. It stands out for its combination of auto and manual tuning, a clear OLED readout and a large 3300mAh battery that supports extended outdoor use, making it a practical tool for portable stations and antenna troubleshooting.

Key Features

• Wide frequency coverage: Supports 1.8MHz to 30MHz so a broad range of HF bands and many radio stations are usable with one device.
• Two tuning modes: Offers both manual and auto tuning so users can quickly match antennas or fine tune when precision is required.
• Portable size: At roughly 154mm x 74mm x 29mm it fits easily into a pack or toolbox for field operations and portable contests.
• Long battery life: Built in 3300mAh lithium battery provides long standby and hours of use after tuning, useful for multi hour portable sessions.
• Multiple status displays: Six status interfaces including a bar power standing meter, large font view and standing curve give quick visual feedback for tuning decisions.

Who It's For

This device is best suited to licensed amateur radio operators, portable DXers and field technicians who need a self contained antenna tuner and SWR/power wavemeter for use with a variety of antennas and transceivers. The lack of requirement for a professional data cable and the small footprint make it ideal for portable operations, emergency communications drills and quick on site antenna checks.

Those who should look elsewhere include users needing VHF/UHF coverage beyond 30MHz or operators who require integrated transceiver control via data protocols; this unit is focused on HF tuning and manual/auto adjustment rather than full remote computer integration.
