Description
Tired of your handheld's stock "rubber ducky" antenna? The Retevis RHD-771 High-Gain Antenna is the upgrade you need to boost your signal, extend your range, and pull in weaker stations. This is one of the easiest and most effective ways to improve your radio's performance.
At approximately 40cm (15.6 inches) long, this flexible whip antenna is a significant performance upgrade over most stock antennas, giving you +2.15dB of gain. It's built for operators who need a reliable signal for their Yaesu, Kenwood, Icom, or Wouxun radios.
Key Features
- 📡Boost Your Range: The high-gain (2.15dB) and longer physical length allow you to transmit and receive signals from further away.
- 💪Flexible & Durable: Made from a flexible material that can bend and take abuse without snapping like a rigid antenna.
- 📶Dual-Band Performance: Fully optimized for both VHF (144MHz) and UHF (430MHz) amateur bands.
- ⚖️Lightweight Design: At only 35g, it adds serious performance without weighing your radio down.
Connector Check: Will This Fit My Radio?
This is the most important step! This antenna has an SMA-Male (SMA-M) connector. Please check your radio before ordering.
✔️ This Antenna (SMA-Male) FITS:
Radios with an SMA-Female connector. This is the common "Japanese style" connector where the radio itself has a center socket and inside threads (e.g., Yaesu, Kenwood, Icom).
❌ This Antenna does NOT fit:
Radios with an SMA-Male connector. This is the "Chinese style" connector where the radio has a center pin (e.g., Baofeng, most Retevis, Ailunce HD1).
Commonly Compatible Radios:
- Yaesu: VX-3R, VX-6R, VX-7R, VX-8R, FT-60R, FT-70DR, and more
- Kenwood: TH-D74, TH-D72, TH-F6A, and more
- Icom: ID-51, ID-52, IC-T70, and more

Questions & Answers

What advantage does one gain by using the "Upgrade" antennae SMA-M 40CM versus the factory supplied unit on the Retevis handheld radio?
A longer antenna made for the operating band offers two advantages.
1. It will help the radio hear weaker signals, thus increasing the range that the radio can recieve.
2. As the antenna offers greater gain, it will "amplifiy" the outgoing singal allowing it to go farther.
