GEPRC SOMA 3.3G is an omnidirectional antenna with high gain, designed specifically for operation in the 3.3 GHz band. The main feature of the model is the use of a protective ABS housing, which prevents deformation of the internal board from wind or mechanical impacts. This ensures a stable signal even during aggressive maneuvering, which is critically important for long-range flights.
The antenna is built on a flexible printed circuit (FPC) and has right-hand circular polarization (RHCP). Thanks to precise tuning, it delivers an average gain of 4.85 dBi with a low standing wave ratio (SWR ≤ 1.44). According to the manufacturer, each unit undergoes testing on a spectrum analyzer to ensure compliance with stated characteristics and maximum video transmission range.
Key advantages:
- High gain of 4.85 dBi significantly extends the range of video communication when paired with powerful 3.3G transmitters.
- Protected housing: a molded ABS plastic shell protects the RF board from external influences and deformations.
- Efficient radiation: the omnidirectional design ensures reliable signal coverage at any drone tilt angle.
- High-quality SMA connector with low impedance, which reduces video transmitter heating and increases system efficiency.
- Optimal length: 170 mm allows the active part of the antenna to be extended beyond the frame and battery for a "clean" signal.
