Product description
The FT K2 omnidirectional drone control antenna is engineered for ExpressLRS and Gemini systems, operating across a wide frequency range of 730–930 MHz. The FT K2 model features a gain of 2.0 ± 0.5 dBi, linear polarization, and an omnidirectional radiation pattern in the horizontal plane.
The vertical beamwidth is approximately 65°, ensuring stable signal coverage within its propagation plane. The radiator is made of Ø 2 mm brass wire, while the mount is crafted from durable molded plastic. Special slots are integrated for quick and secure mounting onto frame arms using zip ties.
The FT K2 is rated for 50 Ohm impedance and a maximum input power of up to 20 W. The radiator length is 365 mm, cable (feeder) length is 150 mm, and total weight is 19 g. Connection is established via a standard IPEX1 (U.FL) connector.
Unlike typical dipole antennas, the K2 features a unique loop design that ensures low VSWR across an expanded frequency range, making it an ideal choice for use with SE4 series receivers.
