HYS
HYS-771N Dual-Band Whip (SMA-Female)
The electrical performance matches the category standard, but at this price with only 80 reviews, a Nagoya NA-771 or a cheaper clone of the same length is the safer buy.
Proprietary RR score
How we scored it
Performance is derived from the antenna's length in wavelengths on each band it covers, not from the advertised gain. How we score →
Length versus wavelength
What 396 mm Buys You
An antenna radiates according to its length measured in wavelengths, not according to the number on the packaging. Here is where this one lands on each band it covers.
| Band | Wavelength | This antenna | Works out as |
|---|---|---|---|
| VHF146 MHz | 2053 mm | 0.19 λ | electrically short |
| UHF435 MHz | 689 mm | 0.57 λ | 5/8 wave |
Decision helper
Is this antenna right for you?
Yes, if you're…
- ✓AnyTone, Baofeng, Wouxun, and Kenwood radios with SMA-Female jacks
- ✓Buyers who specifically want HYS's compatibility list
Skip it, if you're…
- ✕Buyers who want the largest possible review record before trusting an antenna
- ✕Anyone comparing purely on price; cheaper clones offer the same length
Tradeoffs
The good and the bad
What we like
- Same strong electrical length as the category-standard NA-771
- Per-band gain claims are both credible
- Flexible, durable build
What we don't
- Priced like the name-brand original with far fewer reviews to back it up
- Mediocre on 2m, like any whip this length

Overview
The HYS-771N is a 396mm flexible dual-band whip with an SMA-Female connector, the exact length of the market-standard Nagoya NA-771. HYS lists compatibility with AnyTone, Baofeng, and select Wouxun and Kenwood handhelds. It sells for around $19, in the same range as a genuine Nagoya.
At 396mm, the electrical length works out to about 0.19 wavelengths on 2m, mediocre like any whip this size, and about 0.57 wavelengths on 70cm, in the 5/8-wave range that is close to the practical ceiling for a single element. The separate 2.15 dBi (2m) and 2.5 dBi (70cm) claims on the listing are both credible next to what the model predicts. The catch is proof: this antenna has only 80 reviews to date, a fraction of what the Nagoya or the cheaper SMA clones have accumulated, so there is less of a track record to lean on even though the physics look identical.

Key Features
- Boost your handheld radio's range with this 15.6-inch dual band antenna. Tuned for 144 MHz and 430 MHz, it also covers 136-174 MHz and 400-470 MHz, so you get stronger signals across VHF and UHF. Gain reaches 2.15 dBi at 144 MHz and 2.5 dBi at 430 MHz, helping you hear and be heard farther on the trail, at work, or while scanning.
- Made for radios with an SMA male connector. It is a drop-in replacement for the stock antenna on popular handhelds, for Baofeng UV-5R, UV-5R Plus, UV-82, BF-F8HP, and BF-888S, and for many Kenwood, Wouxun, and AnyTone radios. If your radio has an SMA female jack, check your connector before ordering; this antenna will not fit.
- Easy to install and easy to carry. Screw it on in seconds, no tools or tuning needed, and it is light enough for all-day use in a pocket or bag. Swap your short stock antenna for longer range at home, at work, or on the trail, and take it off just as easily when you are done. Built for everyday handheld use, from family outings to emergency preparedness.
- Handles up to 20 watts of input power, so it keeps performing through normal handheld use, repeaters, and higher-power HTs. The low-profile, flexible build stays out of your way while you talk, and the simple one-piece design means there is less to wear out or break over time. No extra adapters or mounts needed, just replace your antenna and go.
- Package includes two HYS-771N SMA female antennas: one orange and one black, so you always have a spare ready. Use one on your radio and keep the backup in your go bag, or share with a friend. A smart upgrade for walkie talkies, scanners, and amateur radios. Actual color may vary slightly from the pictures. Antenna only; radio not included.
