Nagoya NA-320A (Tri-Band)
If you run a tri-band radio that covers 1.25m, the NA-320A is the antenna that matches it. On a plain dual-bander it offers no advantage over the cheaper NA-771.
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 450 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 | 0.22 λ | quarter wave |
| 1.25m223 MHz | 1344 mm | 0.34 λ | between quarter and half wave |
| UHF435 MHz | 689 mm | 0.65 λ | 5/8 wave |
Decision helper
Is this antenna right for you?
Yes, if you're…
- ✓Tri-band radios like the Radioddity GS-10B
- ✓Operators active on the 1.25m band
Skip it, if you're…
- ✕Dual-band-only radios (a standard NA-771 is simpler and cheaper)
- ✕Anyone not using the 1.25m band
Tradeoffs
The good and the bad
What we like
- Covers 2m, 1.25m, and 70cm
- The right match for tri-band radios
- Solid Nagoya build
What we don't
- Only worth it if your radio actually does 1.25m
- Tri-band tuning is a compromise versus a dedicated dual-bander
- Long at 17.7 inches

Overview
The Nagoya NA-320A is a 17.7-inch tri-band whip covering 2 meters, 1.25 meters, and 70 centimeters. It only makes sense if your radio actually transmits on the 1.25m band, which most dual-band handhelds do not.
For a genuine tri-band radio, it is the antenna that matches the radio's coverage. On a plain dual-bander it offers no advantage over a cheaper NA-771, since the extra band tuning is a compromise.
