RAKARJ20 868MHz Whip Antenna Datasheet
Overview
Figure 1: RAKARJ20 Antenna OverviewDescription
The RAKARJ20 868 MHz Whip Antenna is a compact omnidirectional antenna for sub-GHz mesh networking. It is optimized for Meshtastic and similar low-power applications in the EU868 ISM band.
Its vertical polarization and stable impedance matching improve signal reliability. The lightweight whip design supports portable nodes, handheld devices, and fixed gateways. It is suitable where long-range communication and consistent radiation performance are required.
This Whip Antenna also supports LoRa and LoRaWAN IoT applications. It enables reuse across mesh and star network topologies.
