4G Antennas
4G antennas are crucial for boosting signal strength and enhancing connectivity in various applications including 4G gate openers and 4G SMS controllers. They operate within the 4G LTE frequency bands, providing faster data transfer and reduced latency. These antennas improve signal strength in both urban and remote areas.
A standout feature is the magnetic base, making installation quick and easy. You can mount the antenna on any metal surface without permanent fixtures. This is perfect for mobile setups or temporary installations that need flexible positioning. The magnetic base ensures the antenna stays secure, even during movement.
With a 4G antenna, you’ll experience better network performance in weak signal areas. Whether for home routers or industrial machinery, the antenna ensures a reliable and fast connection. This enhanced connectivity is essential for smooth communication and data transmission.
Compact and simple to install, these antennas with magnetic bases are highly versatile. They offer an easy solution for boosting network reliability and speed. Whether stationary or on the move, these antennas deliver seamless connectivity wherever they are used.
Elsema: Frequently Asked Questions
What is the primary purpose of an external 4G antenna?
An external 4G antenna is designed to improve the cellular signal strength for GSM-based devices, such as the Elsema G4000 or G5000 controllers. This is essential in areas with low signal coverage or when the controller is housed inside a metal enclosure that blocks radio waves.
What frequency range do these 4G antennas cover?
Both the 4G Mini and the ANT4GMag are wide-band antennas covering a frequency range from 700 MHz to 2700 MHz. This wide spectrum ensures compatibility with all major Australian cellular networks and supports various 4G/LTE bands for reliable voice and SMS communication.
Can the 4G Mini antenna be mounted directly to the controller?
Yes. The 4G Mini is a compact 16cm whip antenna designed with a standard SMA connection. It can be screwed directly onto the antenna port of a G4000 or G5000 controller, making it an ideal choice for installations where the controller is housed in a non-metal (plastic or polycarbonate) enclosure.
What is the benefit of the ANT4GMag magnetic base?
The ANT4GMag features a magnetic base that allows for rapid, non-permanent installation on any flat metal surface. This is particularly useful for mounting the antenna on the exterior of a steel control cabinet or gate motor housing to ensure the cellular signal is not shielded by the enclosure.
Why shouldn't I keep the 4G Mini antenna inside a metal gate motor?
Metal acts as a Faraday cage, reflecting and absorbing cellular signals. If your 4G controller is inside a metal gate motor or electrical cubicle, the signal will be significantly weakened. Using an external antenna like the ANT4GMag with a lead allows you to mount the receiving element outside the metal, ensuring a reliable connection.
What type of connector do these antennas use?
These antennas typically come with an SMA Male connector. This is the industry standard for most GSM and 4G cellular routers and controllers, including the entire Elsema 4G range.
How long are the cables provided with the antennas?
The ANT4GMag with the magnetic mount come with 3 metres of low-loss coaxial cable. This provides enough length to move the antenna to a high point or outside an enclosure while minimizing signal loss.
How does the ANT4GMag improve reception in remote areas?
By using the 3 metre cable provided with the ANT4GMag, you can position the 22cm whip antenna higher up or away from local obstructions. This flexibility is key in rural or remote areas where moving the antenna just a few metres can be the difference between a failing connection and a stable cellular link.
How do I know if I need a high-gain antenna?
If your 4G controller is frequently dropping offline or the status LEDs is always changing from green to white, an external antenna like the ANT4GMag is recommended.
Is the ANT4GMag weather resistant for Australian conditions?
Yes. The ANT4GMag is rated for outdoor use featuring UV-stabilized. They are designed to withstand the harsh Australian sun and heavy rain when mounted correctly on gate posts or rooftops.
