“WiFi repeater for drone” searches usually mean one of two things: a directional antenna upgrade for your controller (legal, common, and the option covered here), or an RF signal amplifier that boosts transmit power beyond FCC/CE limits (a legal gray area at best, and something we won’t recommend). Directional patch and Yagi antennas work by focusing your existing legal signal in one direction rather than broadcasting it in every direction equally — no illegal power increase, just better-aimed range. Every product below is a passive antenna, not a power amplifier.

The picks, in detail
TBS (Team BlackSheep) Triumph Antenna Set
A widely used circularly-polarized antenna upgrade for 5.8GHz FPV systems, popular for its balance of range and reliability.
- 5.8GHz, RHCP polarization
- Sold as a 2-piece set (TX + RX)
- SMA/RP-SMA connector options
- Well-proven in the FPV community
- Meaningful range/signal-quality improvement over stock stubby antennas
- Requires your controller to have a removable/replaceable antenna connector
TBS Unify Pro 5G8 Linear Antenna
A budget linear-polarized antenna upgrade from the same brand, a low-cost way to test whether an antenna swap solves your range issue.
- 5.8GHz linear polarization
- Compact, lightweight
- Low-cost entry point
- Very inexpensive way to try an antenna upgrade
- Good for controllers/goggles where weight matters
- Linear polarization performs worse through obstructions than RHCP options like the Triumph
RangeVideo 1.2GHz Circular Patch Antenna, 8.6dBi
A directional patch antenna for 1.2GHz long-range FPV systems — aim it at your drone’s flight direction for extended range without amplifying transmit power.
- 1.2GHz, 8.6dBi gain, circular polarization
- Directional patch design
- Ground-station/controller-side use
- Real directional gain without touching transmit power legality
- Good for long-range fixed-flight-path use
- Directional — needs to be aimed roughly at the drone, unlike an omnidirectional antenna
RangeVideo 2.4GHz 8dBi Patch Receiver Antenna
The 2.4GHz equivalent patch antenna, matched to the band most consumer drone controllers (DJI included) actually use.
- 2.4GHz, 8dBi gain
- SMA-Male connector, 30cm cable
- Directional patch design
- Matches the 2.4GHz band most consumer drone remotes use
- Legal directional gain, no amplification
- Directional — best for consistent flight directions, not all-around coverage
ImmersionRC SpiroNET Patch Antenna
A well-known directional patch antenna line from a long-established FPV brand, available in several gain levels.
- 5.8GHz, multiple gain options (8dBi to 13dBi)
- RHCP/LHCP circular polarization options
- Compact patch form factor
- Established, trusted FPV antenna brand
- Multiple gain levels to match your range needs
- 5.8GHz only — check your controller’s operating band before buying
12dBi Dual-Band Yagi Directional Antenna (2.4GHz/5.8GHz)
A dual-band Yagi directional antenna compatible with most consumer drone remote controls, aimed rather than amplified for extra range.
- Dual-band 2.4GHz/5.8GHz
- 12dBi gain, Yagi directional design
- SMA/RP-SMA connector options
- Works across both common consumer drone controller bands
- Noticeable range improvement when aimed correctly
- Must be manually pointed toward the drone — not a set-and-forget solution
Buying tips
- Skip anything marketed as a “signal booster” or “amplifier” that boosts transmit power — the FCC caps unlicensed 2.4GHz/5.8GHz transmit power, and amplifiers that exceed it are a legal gray area, not a real fix.
- A directional antenna (patch or Yagi) improves range by focusing your existing legal signal, not by increasing its power — that’s the legal, common approach FPV pilots actually use.
- Match the antenna’s band (2.4GHz or 5.8GHz) to what your specific controller transmits on — check your drone’s manual before buying.
- Directional antennas need to be roughly aimed at the drone; if you fly in every direction rather than a fixed flight path, the range gain will be smaller in practice.
