Designed for general mobile and wireless use, the antenna supports easier network setup and helps to reduce dropped connections by enhancing both uplink and downlink performance.

Suitable for

• Vehicle installations where a low-profile external antenna is required
• Cellular routers and gateways to increase mobile signal strength
• Portable or fixed wireless devices operating in constrained spaces
• LTE/4G and other cellular network scenarios requiring modest gain

Key specifications

• Gain: 5 dBi to enhance signal reception and transmission
• Form factor: compact straight antenna suitable for low-profile mounting
• Applications: mobile, cellular and wireless devices including routers, gateways and vehicles
• Frequency coverage: designed for cellular and wireless bands (see device compatibility)

How to use

Attach the antenna to a compatible connector on the device using the appropriate cable or mount. Position the antenna vertically for optimal omnidirectional performance and avoid placing it near large metal objects that can obstruct signal propagation. For vehicle installations, secure the antenna to a stable external or internal mounting point and confirm connector compatibility before tightening. After installation, check signal strength and network stability, and adjust placement if needed to achieve the best reception.

Recommendations

Use the TELTONIKA 003R-00281 with devices that support external antennas and verify frequency compatibility with your network operator. For improved results, combine correct antenna placement with updated device firmware and a high-quality coaxial cable to minimise signal loss.
