ABBREE GMRS 42.5-inch Tactical (SMA-Female) vs ABBREE 48.8-inch Foldable Tactical (SMA-Female)

The 48.8-inch Foldable is the clear winner. Both are budget antennas from the same manufacturer with identical connectors and similar prices, but the longer model delivers meaningfully better performance where it matters most.

The single most important differentiator is VHF performance. The 48.8-inch reaches 5/8 wavelength on 146 MHz, delivering a realistic 3.1 dBi gain that actually matches its use case on 2-meter FM. The 42.5-inch GMRS model is electrically oversized at 1.68 wavelengths on 465 MHz, which produces a realistic negative gain of -1.0 dBi. Neither antenna's claimed gain is accurate, but the longer model's overstatement is modest at 2.9 dB compared to the GMRS version's 6 dB exaggeration.

The 42.5-inch GMRS is purpose-built for a narrow band but doesn't perform well even at that job. Buy the GMRS if you operate exclusively on that band and need something extremely compact, though performance expectations should be low. Buy the 48.8-inch Foldable if you want a general-purpose handheld antenna that actually works decently on VHF.

Get the 48.8-inch Foldable unless portability constraints demand the shorter model.
