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

The AR-771C and TD-771 are essentially identical performers. Both measure 385-389 mm and deliver a genuine 5/8 wavelength electrical length at 465 MHz, yielding approximately 3.0-3.1 dBi of real gain. Their claimed 2.15 dBi rating is understated, which is refreshing honesty in a market prone to inflated specs. The physical difference of 4 mm is negligible, and both use identical SMA-Female connectors with flexible construction suitable for handheld radios.

The single differentiator is price: the AR-771C costs $8.95 versus $9.99 for the TD-771, a modest $1.04 advantage. Given their matched electrical performance and identical overall scores of 90/100, this price gap becomes the deciding factor.

Buy the AR-771C if you want to save a dollar on an antenna that delivers the same performance as its competitor. Buy the TD-771 only if you have a specific preference for TidRadio's supply chain or existing brand loyalty.

Choose the AR-771C. It offers identical performance at a lower price, making it the smarter choice for budget-conscious operators who refuse to compromise on antenna fundamentals.
