Zerodrag UFL 2.4GHz T Antenna for ELRS Receivers

The Zerodrag 2.4 GHz T-antenna is a compact, flexible dipole antenna designed as a replacement or upgrade for 2.4 GHz ExpressLRS (ELRS) receivers. Equipped with an industry-standard U.FL (IPEX1) connector, it pairs directly with micro receivers such as the Happymodel EP1, RadioMaster RP1, and BetaFPV Nano/SuperD series across freestyle quadcopters, long-range cruisers, and cinewhoops.

Key features

• Omnidirectional dipole design: Provides balanced radiation coverage for consistent 2.4 GHz control links during dynamic orientation changes.
• Standard U.FL connector: Snaps securely onto 2.4 GHz ELRS receivers utilizing IPEX1/U.FL RF ports.
• Flexible T-element structure: Durable molded arms absorb crashes and impacts without permanent deformation or internal trace breaks.
• Low-profile build: Easy to mount on TPU frame mounts or zip-ties without adding noticeable drag or weight to micro and mini builds.
