This 5.8GHz 2.8dBi RHCP SMA lollipop antenna is designed for optimal performance and range in FPV racing drones. Right-hand circular polarization (RHCP) and 2.8dBi of gain deliver a clear, stable signal, giving racers a competitive edge at high speed.
It is an omnidirectional, circularly polarized antenna with a low standing wave, which means smooth omnidirectional radiation and reception. The cable is 37cm long, which lets you place the antenna where the signal is best.
Upgrading a stock antenna is one of the simplest ways to improve connectivity and precision in a video link.
The listing gives an impedance of 50 ohm, an efficiency of over 50 percent and an operating temperature range of -40 to 85 C, so the antenna copes with cold mornings at the field and warm days alike. It is supplied singly, as the long version of the lollipop antenna, with a 37cm cable.
Omnidirectional: it radiates and receives in all directions around the aircraft.
Circular polarization (RHCP): matches the polarization used by most FPV video systems.
2.8dBi gain: a modest gain that keeps the pattern wide and stable.
Low standing wave: smooth, efficient radiation.
37cm cable: flexibility in where the antenna is mounted.
FPV video systems use circular polarization because it stays reliable when the aircraft banks and turns. Antennas of the same handedness, such as RHCP with RHCP, pair best, and this antenna is right-hand circular.
A lollipop antenna gets its name from the round head on a stalk. It is a compact way to build a circularly polarized omnidirectional antenna, and the SMA connector allows it to attach to a range of transmitters and receivers.

Replacing a damaged or weak stock antenna
Improving signal clarity in high-speed racing
General 5.8GHz FPV use
The antenna uses an SMA connector, has a 50 ohm impedance and can handle up to 50W. Check that your transmitter or receiver uses the same SMA gender and polarity before you order.
Keep the antenna away from carbon fibre and metal, and protect the cable from propeller contact.
