Choosing a tuner for ham radio antennas means balancing a stated range reaching 60 MHz and mobile flexibility against automatic operation and a smaller outlay. The MFJ-945E and HamGeek ATU-100 Pro+ approach that decision differently, so the right pick depends on your antenna setup, operating mode, and power ceiling.
Quick verdict
Choose the Nice MFJ-945E Mobile Tuner when mobile, travel, or home-station flexibility is the priority. Choose the HamGeek ATU-100 Pro+ when automatic operation and a lower listed price matter more. The listed prices are $149.99 and $64.60, an absolute spread of $85.39.

Where each wins
MFJ-945E: power handling and metering
The MFJ-945E has the stronger case when its listed 300-watt transmit power handling fits the station. Its dual/cross-needle front-panel meter can display forward and reflected power or SWR values simultaneously, giving the operator two distinct display modes in one tuner.
HamGeek ATU-100 Pro+: automatic operation and display
The HamGeek stands out for its automatic tuner format, 0.96-inch OLED display, and included USB cable. A two-year manufacturer warranty is also listed, giving this tuner a clearly stated ownership detail that the MFJ comparison does not include.
Product notes
Nice MFJ-945E Mobile Tuner
The MFJ-945E is a flexible match for an antenna setup that may change between coax-fed dipoles, quads, verticals, yagis, and a single-wire antenna. Its description also names mobile whip antennas, travel operation, and a home station, while the listed 1.8-60 MHz span covers HF and 6-meter VHF. That combination gives the tuner several clearly described operating roles. The limitations are concrete: the unit is listed as used, and the external rear-panel +12VDC supply needed to illuminate the meter is not included. Choose the MFJ when its antenna flexibility and stated band coverage matter more than an automatic format.
HamGeek ATU-100 Pro+
The HamGeek ATU-100 Pro+ makes sense for a setup centered on automatic tuning across its stated 1.8-50 MHz range. It is assembled with a shell, and the package includes a USB cable and user manual. The main limitation is the 100W maximum working-power specification; 150W is described separately as the maximum possible measured power, not as the working-power rating. The tuner also calls for a 10-15V DC supply range, so the operating setup must fit that input. Choose the HamGeek when automatic operation suits the station and the 1.8-50 MHz range is sufficient, rather than selecting it for the MFJ's stated 60 MHz endpoint.
Final choice by use case
- For mobile whip, travel, or home-station use: choose the Nice MFJ-945E Mobile Tuner, whose description explicitly names all three roles.
- For a tuner with a dual/cross-needle meter and listed 300-watt transmit handling: choose the MFJ-945E.
- For a setup that fits a 10-15V DC input and 100W maximum working power: choose the HamGeek ATU-100 Pro+.
- For automatic operation with an OLED display: choose the HamGeek ATU-100 Pro+.
