ABBREE 48.8-inch Foldable Tactical (SMA-Female) vs Retevis RHD-771 (SMA-Female)

The Retevis RHD-771 is the winner for most users, despite the ABBREE's longer physical length.

The single most important factor is electrical length on the bands you actually use. The ABBREE is optimized for VHF at 0.60 wavelengths, delivering realistic 3.1 dBi gain, but it performs poorly on UHF at 1.80 wavelengths where it drops to negative gain. The Retevis reverses this: it's electrically short on VHF at minus 1.0 dBi but hits the sweet 5/8 wave point on UHF at 2.9 dBi. The ABBREE also oversells its capabilities by about 3 dB, claiming 6 dBi when its length supports only 3.1 dBi. The Retevis makes honest claims backed by its actual dimensions.

The ABBREE suits users who primarily operate VHF repeaters and need a more compact folding form factor. The Retevis is the better choice for balanced VHF/UHF work or anyone prioritizing UHF performance on a handheld.

Buy the Retevis RHD-771. It delivers genuine performance across both bands, costs less, and the higher overall score reflects its straightforward engineering without marketing overstatement.
