ABBREE AR-771C GMRS (SMA-Female) vs TIDRADIO TD-771 GMRS (SMA-Female)

The AR-771C and TD-771 are effectively matched. Both are 5/8 wave designs delivering realistic 3.0-3.1 dBi gain on GMRS, with identical electrical performance on the band. Claimed gain specs are both optimistic but typical for this category. Physical lengths differ by only 4 mm, which is negligible.

The single most important differentiator is price. The AR-771C costs $8.95 versus $9.99 for the TD-771, a $1.04 gap. Both carry 4.6/5 owner ratings from comparable review populations, so buyers report similar satisfaction with each.

The AR-771C makes sense if you want the same performance for less money. The TD-771 makes sense only if you have a specific reason to prefer it, which the available data does not reveal.

For most buyers, get the AR-771C. You save a dollar on identical specs and equal owner satisfaction. If stock runs out or you already have TD-771 spares on hand, the TD-771 performs identically and the price difference is negligible enough not to matter.
