Description
Overview
The BETAFPV Dipole T Antenna is designed and manufactured by BETAFPV for 2.4G/915MHz/868MHz receivers. It is an omnidirectional antenna and includes an RF balun circuit inside the injected rubber enclosure. Each antenna is tested with a frequency spectrograph to ensure correct operating status.
Key Features
- Omnidirectional dipole T design
- RF balun circuit integrated inside the injected rubber enclosure (“RF Balun Circuit Inside”)
- U.FL connector compatibility (works with any receiver that uses a U.FL connector)
- Frequency versions: 2.4G, 915MHz, 868MHz (do not use the wrong frequency version; internal balun circuits differ)
- Length options (from product labeling):
- White for 2.4G: 46mm/80mm coaxial cable length options
- Blue for 915MHz/868MHz: 80mm coaxial cable length for full range performance
- Blue for 915MHz/868MHz: 46mm coaxial cable length; cannot expect full range; suitable for Toothpick and Whoop drones

RF Antenna Balun
In order for balanced antennas to be fed by coaxial cable, an antenna balun is often included at the feed point. This antennas balun circuit is located inside the injected rubber enclosure. A basic concept diagram references the Dipole centre & balun with an Unbalanced feeder. For more background information, refer to: What is a Balun: RF Antenna Balun.
Whats Included
- 2 x BETAFPV T antenna
Details
The BETAFPV Dipole T Antenna is a lightweight omnidirectional option for 2.4G, 915MHz, and 868MHz receiver builds.
Choose the correct frequency version and coax length2.4G uses white leads, while 915/868MHz uses blue leads with 80mm recommended for full-range setups.
Omnidirectional radiation supports consistent link performance as the drone changes orientation in flight.
An integrated RF balun circuit sits inside the injected rubber enclosure to match the dipole to a coax feed.
