Comet
Comet SMA-24 (SMA-Male)
The premium choice for SMA-Male radios. You pay for Comet's build quality more than for a big performance jump, but it is the whip that will not let you down.
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 |
| UHF435 MHz | 689 mm | 0.65 λ | 5/8 wave |

Overview
The Comet SMA-24 is the SMA-Male version of Comet's premium superflex dual-band whip, built for radios with an SMA-Male antenna jack. It gives Yaesu, Kenwood, and TYT owners a high-quality alternative to the Nagoya whips.
Like the SMA-24J, it is a 17.7-inch superflex element with strong 70cm performance and build quality well above the cheap clones. Confirm your radio uses an SMA-Male jack before buying.
