Product overview
The GEPRC 868MHz/915MHz 2.4G Tri-Band Stick Antenna provides omnidirectional signal reception through a linearly polarized PCB antenna. Its three operating bands cover 860-870MHz, 900-930MHz and 2400-2500MHz, with respective center frequencies of 865MHz, 915MHz and 2450MHz. Reception is optimized at a vertical angle, making orientation a relevant integration consideration. The specified gains are 2.8dBi, 2.82dBi and 2.97dBi respectively; radiation efficiency also varies by band, at 49%, 51% and 68%. Cross-polarization suppression is specified as -25dB.
The physical assembly combines a PCB antenna with an injection-molded ABS shell in an oval, low-drag shape. Its 172mm length and 11.2g weight define the space and mass to accommodate during installation, while the SMA connector defines the connection interface. The supplied configuration contains one tri-band stick antenna, an antenna accessory rather than a flight platform or airframe kit. Its VSWR specification is ≤1.5, alongside the individual band coverage, gain and efficiency figures that characterize its radio-frequency performance.
