Antenna TELTONIKA PR1KRF30 — 2.4–2.5 GHz 3 dBi RP-SMA male, linear polarization, 50 Ω, 30×82.8 mm

The Teltonika PR1KRF30 is a compact external antenna designed for the 2.4–2.5 GHz frequency band. With a 3 dBi nominal gain, linear polarization and a male RP‑SMA connector, this antenna provides a simple, space-saving option to improve wireless link quality for routers, modems and IoT gateways. The antenna has a characteristic impedance of 50 Ω, a black finish and dimensions of 30 × 82.8 mm, making it suitable for desktop, wall-mounted or cabinet installations where a short, durable external antenna is required.

Advantages

The antenna’s 3 dBi gain delivers moderate signal strengthening without significantly altering radiation pattern, helping maintain stable coverage within the 2.4–2.5 GHz band. The RP‑SMA male connector ensures wide compatibility with many networking devices and enables easy replacement or upgrade. Its compact physical size and 50 Ω impedance provide straightforward integration into existing Wi‑Fi and wireless IoT systems while its linear polarization supports predictable link behaviour in typical indoor and light commercial environments.

Suitable for

• Improving Wi‑Fi signal strength for home and small office routers
• External antenna for 2.4 GHz IoT gateways and modems
• Short-range wireless links and device testing where a compact antenna is required
• Replacement of stock antennas on compatible networking equipment using RP‑SMA male

Key specifications

• Frequency band: 2.4–2.5 GHz
• Gain: 3 dBi
• Connector type: RP‑SMA male
• Polarization: linear
• Impedance: 50 Ω
• Colour: black
• Dimensions: 30 × 82.8 mm

How to use

Connect the RP‑SMA male connector to a compatible female RP‑SMA socket on the router, modem or IoT device. Position the antenna vertically for standard linear polarization alignment and adjust orientation slightly to optimise received signal strength and link stability. For devices mounted in enclosures or behind panels, place the antenna where it has a clear line of sight to the covered area when possible. No additional configuration is required in device software after physical installation.

Recommendations

For best performance, avoid placing the antenna directly adjacent to large metal surfaces or other antennas that may cause detuning or interference. Use the antenna in the intended 2.4–2.5 GHz band and verify connector compatibility before installation. Where possible, test different positions and orientations to find the optimal balance between coverage and signal quality.
