Retevis RHD-771 (SMA-Female)
The RHD-771 is the value play: NA-771-class performance for less, from a known brand. If you are outfitting more than one radio, the multi-packs make it the cheapest honest upgrade.
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 391 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 |

Overview
The Retevis RHD-771 is a 15.4-inch dual-band whip in the same mold as the Nagoya NA-771, with an SMA-Female connector for Baofeng-style radios. It frequently sells for less than a genuine Nagoya, especially in multi-packs.
Performance is in the same 2.15 dBi class, and Retevis is an established radio-accessory brand rather than an anonymous seller. It is a sensible budget pick when you want to upgrade several radios at once.
