CDMA-5 450 MHz Directional Antenna 6 dBi – 5 m Cable with TNC Connector

Give your 450 MHz connection better reception opportunities with CDMA-5 – a compact directional antenna with a stated gain of 6 dBi and a permanently attached 5-metre cable. It is designed for compatible routers, modems and communication equipment operating within 400–470 MHz, with a particular focus on the 450 MHz band.

When the equipment’s built-in antenna provides insufficient reception, an external antenna in a better position can be a practical solution. CDMA-5 can be installed outdoors and aligned towards a suitable base station, while the connected equipment remains indoors. This allows you to find a better reception point without relocating the entire installation.

Its five-element construction provides directional transmission and reception. Aligning the antenna towards the base station that delivers the best results can improve the conditions for a stable data connection. The design suits fixed installations where reception is needed from a selected direction.

At 57 cm long, with a stated weight of 0.53 kg, CDMA-5 is a convenient option when mounting space is limited or a smaller antenna is preferred on a wall-mounted pole. It includes a mast bracket and integrated cable, simplifying installation and reducing the number of separate parts to handle.

The 5-metre cable terminates in a TNC connector. Check that the equipment’s antenna input matches the connector type and that its operating frequencies fall within the antenna’s specified range.

CDMA-5 suits users looking for a smaller external directional antenna for a fixed 450 MHz installation. Suitable positioning and careful alignment can help improve reception and connection stability. Actual results depend on the available signal, surroundings, cable losses and connected equipment.

✅ Benefits

• Designed for the 450 MHz band. Specified frequency coverage is 400–470 MHz.
• Stated antenna gain of 6 dBi. Directional design for compatible communication equipment.
• Compact five-element construction. The antenna is just 57 cm long.
• External positioning for better reception opportunities. Allows outdoor installation where the signal may be stronger.
• Permanently attached 5-metre cable. Supplied with a TNC connector for compatible equipment.
• Mast bracket included. For fixed installation on a suitable pole.
• Vertical polarisation and 50 Ω impedance. Clearly specified connection requirements.

🎯 Ideal for

• 450 MHz routers and modems with a compatible TNC antenna connection.
• Fixed data connections where built-in antennas provide insufficient reception.
• Homes, holiday properties and smaller business premises with a suitable outdoor mounting position.
• Installations where a compact directional antenna is easier to position.
• Mounting on an antenna mast or wall-mounted pole.

🔧 Connection and use

Check that the equipment operates within 400–470 MHz and has an antenna input compatible with the cable’s TNC connector.

Install the antenna on a stable pole using the included mast bracket. For wall installation, use a suitable wall bracket or wall-mounted pole. For vertical polarisation, the antenna elements must be upright.

Align the antenna towards a suitable base station and adjust the direction in small steps. Allow the equipment to update its signal readings between adjustments. Compare signal quality and connection stability before securing the final position.

Route the 5-metre cable without sharp bends. Provide strain relief at the mounting point, protect exposed connections against moisture and avoid unnecessary cable extensions.
