Abbree AR-152 Folding Tactical Antenna vs TIDRADIO TD-771 GMRS (SMA-Female)

The TD-771 is the clear winner here. Both cost the same, but the TD-771 delivers honest performance while the AR-152 oversells itself.

The single most important difference is antenna design matched to purpose. The TD-771 is a 5/8-wave antenna optimized for GMRS at 465 MHz, where it achieves a realistic 3.0 dBi gain with claimed specs that actually align with its physical length. The AR-152 tries to serve multiple bands with a single length, and it struggles. At VHF it manages half-wave performance (2.6 dBi), but the manufacturer claims 5 dBi, which is misleading. At UHF, its multi-wavelength electrical length produces negative gain, making it a poor choice for 435 MHz.

The AR-152 appeals to users wanting a compact folding antenna for dual-band radios who can tolerate average VHF performance and accept that it won't work well on UHF. The TD-771 is the better choice for anyone with a GMRS radio or who values honest specifications and practical single-band optimization.

Buy the TD-771. Its 3.0 dBi realistic gain, accurate manufacturer claims, and higher overall score make it the sensible purchase at this price point.
