Network antenna TELTONIKA PR1KCL25, 2.5 dBi, 0.698–0.96 / 1.71–2.69 GHz, SMA male, linear polarization

The Teltonika PR1KCL25 is a compact network antenna designed for improving cellular and wireless connectivity across the 0.698–0.96 GHz and 1.71–2.69 GHz frequency ranges. With a maximum gain of 2.5 dBi and a male SMA connector, this low-profile antenna is intended for use with routers, gateways and IoT devices in indoor and sheltered outdoor environments. The antenna's linear polarization and compact dimensions (15 mm height, 80 mm diameter) make it suitable where space is limited and a discreet installation is required.

Advantages

The antenna provides modest gain across key cellular bands, helping enhance signal reception and transmission for devices that use those frequencies. Its SMA male connector enables direct connection to many commercial routers and gateways without additional adapters. The compact, low-profile design reduces visual impact and simplifies mounting in confined or visible areas, while the lightweight construction eases handling and installation.

Suitable for

• Improving cellular signal for indoor routers and gateways
• IoT devices requiring external antenna connectivity
• Sheltered outdoor installations such as covered porches or equipment cabinets
• Space-constrained setups where a low-profile antenna is needed

Key specifications

How to use

Attach the SMA male connector to the corresponding SMA female port on your router, gateway or IoT device. Ensure the connector is tightened by hand until secure; avoid excessive torque to prevent damage to the connector. Position the antenna vertically for optimal reception when using linear polarization unless specific orientation is recommended by the device manufacturer. If the device will operate outdoors but under shelter, mount the antenna where it has a clear line of sight to the signal source while remaining protected from direct weather exposure.

Usage recommendations

For best results, test antenna placement and orientation to identify the location that yields the strongest signal. Use short, high-quality jumper cables or direct connection whenever possible to minimize signal loss. If a different connector type is required, use an appropriate adapter rated for the same frequency ranges. Avoid mounting near large metal objects or other antennas that could cause interference.
