This article covers Bingfu 4G LTE アンテナアダプター SMAメス.

Overview

The Bingfu 4G LTE Antenna Adapter is a coaxial pigtail cable that converts an SMA female connector to a TS9 plug. With a short 15cm length, it is designed to connect directly to the external antenna ports of mobile hotspots and USB modems. The package includes two cables, providing a spare or allowing use with multiple devices.
This adapter enables you to attach an external antenna to improve signal reception in areas with weak cellular coverage. It uses 50-ohm impedance and RG174 cable, offering a good balance of flexibility and durability for everyday use.

Connectivity & Compatibility

The adapter features an SMA female (bulkhead mount) on one end and a TS9 plug on the other. TS9 is a compact connector commonly found on mobile broadband devices. Compatible devices include a wide range of Huawei hotspots (E8372, E589, E5787 series, etc.), ZTE MiFi routers (MF980, MF971V, MF970, etc.), and USB modem dongles (Huawei E8278, E398, ZTE MF82, etc.).
Connection is straightforward: plug the TS9 end into your device's antenna port, then screw an external antenna with an SMA male connector onto the SMA female end. The 15cm cable length keeps the external antenna close to the device, minimizing signal loss over the pigtail.

Product Info

This product is sold under the Bingfu brand and is available on online retailers. The price for a 2-pack is around ¥3,000, making it an affordable entry-level solution. Warranty typically includes a 30-day return policy from the seller. The package contains only the two cables; you will need to purchase an external antenna separately.
Market positioning is budget-friendly, targeting users who want to experiment with external antenna connectivity without a significant investment. While it may not offer the shielding or build quality of premium brands, it provides adequate performance for most casual and semi-professional use cases.

Best Use Cases

  • Mobile hotspot users: Ideal for campers, RV travelers, or anyone using a portable Wi-Fi hotspot in areas with weak signal. By connecting an external antenna via this adapter, you can significantly improve reception and connection stability. Note that you'll need to buy a compatible antenna separately.
  • USB modem users: If you use a USB dongle modem with your laptop and struggle with poor signal, this adapter allows you to attach an external antenna for better throughput. Check device compatibility before purchasing.
  • DIY antenna enthusiasts: For those building custom or directional antennas, the SMA female connector is a standard interface that works with many aftermarket antennas. The short cable length is ideal when the antenna is mounted close to the device.
  • Spare cable kit: With two cables in the pack, you can keep one as a backup or use them with different devices. The low cost makes it easy to have a dedicated adapter for each hotspot or modem.
