Antena de rede TELTONIKA PR1US440, ganho de 3 dBi, 0,698–0,96 / 1,71–2,69 GHz, ficha SMA, 50 Ω, 198 mm, polarização linear, preto

The Teltonika PR1US440 is a compact network antenna with 3 dBi gain, designed for both mobile and fixed wireless installations. It supports the frequency ranges 0.698–0.96 GHz and 1.71–2.69 GHz, offers 50 Ω impedance and linear polarization, and features an SMA male connector for straightforward mounting. With a 198 mm length and black finish, this antenna is suitable for routers, modems and IoT gateways where space is limited but stable reception is required.

Advantages

The antenna’s dual-band coverage enables compatibility with multiple cellular and wireless systems across low and mid bands, while the 3 dBi gain balances signal reach and compact size. Linear polarization and 50 Ω impedance ensure predictable performance with standard network equipment. The SMA male connector simplifies installation on devices with an SMA female port, and the 198 mm profile allows for discreet placement on indoor or outdoor enclosures.

Suitable for

• Cellular routers and 4G/3G modems requiring external antennas
• IoT gateways and telemetry devices operating in the listed frequency ranges
• Fixed wireless access points in small installations
• Mobile or vehicular routers where compact antenna length is necessary

Key specifications

• Antenna gain: 3 dBi (maximum)
• Frequency ranges: 0.698–0.96 GHz and 1.71–2.69 GHz
• Impedance: 50 Ω
• Polarization: Linear
• Connector type: SMA male
• Length: 198 mm

How to use

Connect the SMA male connector of the antenna to the SMA female port on your router, modem or gateway. Position the antenna vertically for best omnidirectional performance and avoid placing it directly next to large metal objects that can obstruct signal propagation. For outdoor installations, ensure any mounting point and cable routing maintain the device’s ingress protection and do not place undue strain on the connector.

Recommendations

Use the antenna in environments matching the specified frequency bands to ensure optimal connectivity. If signal strength remains low, try adjusting the antenna orientation or relocating the host device to a higher or more open position. When connecting to devices with different connector types, use an appropriate, low-loss adapter or cable rated for 50 Ω to preserve signal quality.
