If you're shopping for ham radio antennas, the first question is not which model has more numbers-it's whether you need an antenna or an antenna tuner. The Shortwave AM MW FM External Antenna is built around portable HF and shortwave reception, while the HamGeek ATU-100 Pro+ is an automatic tuning unit. They solve different setup problems, so the clearest choice comes from your radio's next missing component.
Quick verdict
For a receiver that needs an external wire, choose the Shortwave AM MW FM External Antenna. Its portable format and RCA-jack compatibility make it the direct match for the reception-focused use described. Choose the HamGeek ATU-100 Pro+ when the needed component is an automatic tuner covering the stated 1.8-50 MHz range and 100W maximum working power. At the two listed prices, the gap is $49.61, but the role difference matters more than the price difference.

Where each product wins
Shortwave AM MW FM External Antenna
- Reception first: Its description focuses on enhancing signal reception, while the title names AM, MW, FM, and shortwave external antenna use.
- Portable receiver setup: The 25ft portable wire format and RCA-jack compatibility give it a defined use case with a compatible radio.
HamGeek ATU-100 Pro+
- Automatic tuning: The title and automatic type make its role clear; the assembled unit with a 0.96-inch OLED display is relevant when tuning is the requirement.
- Tuner-focused systems: Its stated operating range and power specification give shoppers concrete selection points without treating a larger number as automatically better.
Product notes
Shortwave AM MW FM External Antenna
Choose the Shortwave AM MW FM External Antenna when the immediate task is adding a portable wire for HF or shortwave reception. The description gives it a 25ft format and names the Realistic DX440 and Sangean 803A, along with radios using an RCA jack, so its intended setup is clear. The title also keeps AM, MW, and FM in view, while the attributes identify HF and SW-HF bands. The limitation is its role: this is the reception-focused antenna choice, not the automatic-tuner choice represented by HamGeek. If the missing piece in your station is tuning hardware rather than an external receiving wire, its straightforward antenna format will not address that need.
HamGeek ATU-100 Pro+ Automatic Antenna Tuner
Pick the HamGeek ATU-100 Pro+ Automatic Antenna Tuner when your station needs an automatic tuner instead of a receiving wire. Its stated 1.8-50 MHz frequency range, 100W maximum working power, and 10-15V DC supply range define the operating envelope. The package includes a USB cable and user manual, and a 2-year manufacturer warranty is listed. The limitation is role: the title identifies a tuner, so it does not take the place of the Shortwave antenna's external-wire reception job. Choose it for the automatic tuning function and its stated operating specifications; choose the other product when the physical antenna itself is what your receiver setup lacks.
Final choice by use case
- For a portable shortwave receiver needing an external antenna: choose the Shortwave AM MW FM External Antenna because its named role and description center on reception rather than tuning.
- For a station needing automatic tuning: choose the HamGeek ATU-100 Pro+ because automatic tuning is its explicit product role, supported by its stated frequency and power specifications.
- For the lower listed price: choose the Shortwave antenna; the two products have a $49.61 listed-price spread.
The practical takeaway is straightforward: the Shortwave model adds an external reception wire, while the HamGeek unit adds automatic tuning hardware. Select the one that fills that specific gap in your setup.
