Product description
The 868 MHz Yagi Antenna is a weatherproof, range-boosting antenna that delivers 9 dBi of directional gain in the 865–868 MHz LoRa/LoRaWAN band. With its N-female connector, 30 cm RG58 cable, and 50 Ω impedance, it is ready to connect directly to a gateway or device.
868 MHz Yagi Antenna 9 dBi — LoRa/LoRaWAN Range Solution
The 868 MHz Yagi Antenna is an outdoor antenna with 9 dBi of directional gain operating in the 865–868 MHz LoRa/LoRaWAN band. Unlike omnidirectional antennas, it focuses energy in a single direction, significantly extending range and signal quality between remote sensor nodes and the gateway. It is ideal for open fields, farmland beyond hilltops, or any installation that requires a clear line of sight between the gateway and the station.
Where Is It Used?
- LoRaWAN range extension: Establishes a directional link between the gateway and a remote agricultural climate station / soil moisture sensor.
- Rugged/remote terrain: Installations where an omnidirectional antenna falls short and single-direction gain is required.
- Point-to-point links: Stable, low-loss 868 MHz communication between two fixed points.
Choosing an Antenna for LoRa Installations
Omnidirectional antennas suit a central hub/gateway that must collect data from every direction, while a Yagi antenna provides higher gain and stability for reaching a remote point in a specific direction. For remote sensors experiencing range issues, a directional Yagi antenna is often the most cost-effective solution.
Frequently Asked Questions
Sıkça Sorulan Sorular
Yagi anten çok yönlü antenden farkı nedir?
Yagi anten yönlüdür; enerjiyi tek doğrultuda odaklayarak o yöndeki uzak noktaya daha yüksek kazanç ve kararlı bağlantı sağlar. Çok yönlü anten ise her yönden sinyal alır, merkez/gateway için uygundur.
Hangi bantta çalışır?
865–868 MHz LoRa/LoRaWAN bandında çalışır ve 9 dBi kazanç sunar.
Bağlantı ve kablo tipi nedir?
N dişi (N Female) konnektör ve 30 cm RG58U kablo ile gelir; empedans 50 Ω'dur.
Dış mekana uygun mu?
Evet. Alüminyum alaşım gövde, DC topraklamalı yıldırım koruması, -40/+70 °C çalışma sıcaklığı ve 60 m/s rüzgar dayanımına sahiptir.
Nasıl monte edilir?
Ø30–Ø50 mm çapındaki direklere montaj aparatıyla sabitlenir ve hedeflenen yöne çevrilir.
