Antenna Teltonika PR1KRT25 2.5 dBi RP-SMA 2.4-2.5 GHz

The Teltonika PR1KRT25 is a compact external antenna designed for wireless networking in the 2.4–2.5 GHz band. With a 2.5 dBi gain and linear polarization, this RP-SMA male connector antenna is intended to improve signal reception and transmission for routers, gateways and other wireless devices. Its small footprint (30 mm width, 82.8 mm height) supports space-conscious installations while maintaining stable performance across Wi‑Fi and other ISM-band applications.

Advantages

The antenna delivers a modest gain of 2.5 dBi to enhance link reliability without significantly altering the radiation pattern, making it suitable where omnidirectional coverage and predictable performance are required. The RP-SMA male interface enables straightforward connection to compatible equipment. The linear polarization reduces cross-polarization loss when paired with like-polarized devices. Its compact dimensions and lightweight construction facilitate easy mounting and repositioning for optimal positioning.

Suitable for

• Improving Wi‑Fi signal strength for routers, access points and IoT gateways operating at 2.4 GHz
• Extending range or stabilizing links in ISM-band wireless setups
• Indoor and sheltered outdoor deployments where a small omnidirectional antenna is needed

Key specifications

• Frequency band: 2.4–2.5 GHz
• Gain: 2.5 dBi
• Connector type: RP‑SMA male
• Polarization: linear
• Dimensions: width 30 mm, height 82.8 mm
• Radiation pattern: approximately omnidirectional

How to use

Attach the RP‑SMA male connector to a compatible RP‑SMA female socket on your router, modem or wireless gateway. Position the antenna vertically to achieve the intended polarization and omnidirectional coverage. For best results, mount the antenna clear of large metal objects and at a suitable height to reduce obstructions between communicating devices. Check device manuals for any required torque limits when tightening the connector to avoid damage.

Recommendations

Use the Teltonika PR1KRT25 when you need a compact, low‑gain antenna to stabilize or modestly extend 2.4 GHz links. For larger coverage needs consider higher-gain or directional antennas; for mixed-polarization environments ensure device and antenna polarizations match to minimize signal loss.
