Directly attached, immediately better: 4G reception without detours
Forget complicated installations and signal losses due to long cables. The ALFA AOA-4G-2ACM is designed as a 4G Antenna for direct connection. You screw it with its integrated N-connector directly onto the N-socket of your Outdoor Router, such as the ALFA Tube-U4Gv2 or models from Teltonika. The result is a clean, mechanically stable, and electrically optimal connection that gets the most out of the incoming signal and stabilizes your data rate.
Built for any weather, made for outdoor use
This Antenna is more than just a piece of technology – it is a reliable outdoor partner. As a weatherproof 4G 4G Outdoor Antenna, it withstands rain, snow, and extreme temperatures from arctic -40 °C to hot +85 °C. Its robust construction ensures that your connection remains stable even under demanding environmental conditions. This makes it the perfect choice for permanently installed IoT gateways, camera systems, or use on vehicles and campers.
360° Freedom: No alignment, just reception
The biggest advantage of an Omni 4G Outdoor Antenna is its simplicity. You don't need to know where the nearest transmission mast is. The AOA-4G-2ACM receives signals equally from all directions. This is ideal for mobile applications such as on boats or in motorhomes, but also for stationary setups where the signal source can change or precise alignment would be cumbersome. Simply mount it and enjoy a more stable connection.
Realistic gain for stable connections
With an antenna gain of up to 2 dBi, the ALFA 4G Antenna N-connector is designed to solidify a weak or unstable connection. It is not a range miracle for areas completely without reception, but it is extremely effective in improving signal quality exactly where it matters most: directly at the device. It can make the difference between a constantly dropping and a consistently stable data connection and is one of the most important 4G Outdoor Antennas for on-site signal optimization.

Frequently Asked Questions (FAQ)
Is the ALFA AOA-4G-2ACM suitable for mast mounting?
No, it is a stick antenna with an N-connector for direct mounting on a device. It does not have its own bracket for mast attachment.
Does this antenna improve my 5G reception?
No. The frequency bands are specified for 4G/LTE networks. 5G requires different, higher frequency ranges that are not covered by this antenna.
Do I need an additional cable for connection?
No, the antenna is screwed directly onto an N-socket on the router or modem. A cable is only needed if the end device does not have an N-socket.
What does '2 dBi gain' mean in practice?
A gain of 2 dBi means a slight but measurable improvement in signal strength. It helps to stabilize an unstable connection but will not work wonders in areas with very poor reception.
Is the antenna waterproof?
Yes, it is designed as an outdoor antenna and protected against weather influences such as rain and humidity to ensure reliable outdoor operation.
Can I use this antenna for WiFi?
No, the frequency ranges are optimized for mobile communication (4G/LTE). The antenna is not tuned for WiFi applications on 2.4 GHz or 5 GHz and would only function suboptimally there.
