Updated Aug 2026Radtel RT-493 vs Retevis A3
Our pick
Radtel RT-493$32.99
The Radtel RT-493 is the clear winner here. Despite both radios lacking modern features like DMR, APRS, and GPS, the RT-493 delivers substantially better overall performance at less than half the price. With a confirmed 10W transmit power and a significantly higher review score of 59 versus 31, it outperforms the Retevis A3 across the board. The A3's transmit power is listed as unknown, which is already a red flag for a radio at this price point, and its dramatically lower score suggests meaningful performance deficiencies that the higher price tag fails to justify.
The single most important differentiator is the review score gap. A 28-point difference indicates the RT-493 is fundamentally more reliable and capable for amateur radio operations.
The RT-493 is ideal for budget-conscious operators who need straightforward VHF/UHF performance without premium features. The Retevis A3 might appeal only to someone who already owns one and needs a replacement or has specific compatibility requirements with existing equipment.
For anyone shopping between these two, buy the Radtel RT-493 without hesitation. You'll save money while getting a radio that actually performs.
