TurboTenna 11N PRO
18dBi Waveguide 2.4GHz antenna

The TurboTenna 11N PRO is a 2.4GHz cAntenna.

In the early days, it was called a Pringles cAntenna because it was made of a can after the chips were consumed. The word cAntenna is created by combining the first letter of a can or "c" with the word "Antenna". The Pringles, albeit conveniently available in a supermarket, is not perfectly ideal for constructing a waveguide antenna - the thin and flimsy internal foil and the narrow opening offers less gain and smaller aperture than it should be.

The 11N PRO was created to overcome these shortcomings.

So, why are people so interested in it? It is probably because they are fascinated by how a signal gain is made possible by creating such a simple canister structure that holds a standing wave resonant with the wireless carrier frequency. It is analogous to a vibrant trumpet in which the sound is amplified when the standing wave is resonant with the tone of the mouth piece. Higher efficiency means you make more sound with less effort. Likewise, a highly efficient antenna picks up a further remote signal with less RF power.

This simple device offers an opportunity to stir up an authentic interest in physics and science. Hence we have packaged components as DIY kits that you could work with the kids to build your own cAntenna from 2.4GHz to 5GHz using an Aluminium tube in practical terms or a Pringles tube more on experimental purpose.

For those who simply want to buy a high gain directional antenna to work with your own Wi-Fi dongles and routers, then the 11N PRO is the professional finished product for you.

Building a cAntenna on your own may sound simple, the key components are nothing more than an open ended metel tube, a copper pin on a Chassis Mount N-female connector, a mini tripod and a cap. But finding a metal can with an optimal geometry, the pin and their physical positioning could make a huge difference in performance.

Our engineers have optimized every aspect of the cAntenna design and turned it into the TurboTenna 11N PRO cAntenna for wireless LAN range extension and coverage, delivering a remarkable gain of 18dBi, way beyond the built-in factory rubber duck antenna of most popular wireless routers and Wi-Fi adapters.

This translates into a greater range from several hundred feet to several miles, depending on the power of the Wi-Fi dongle, the atmospheric and other propagation conditions such as trees, hills, the length of cable, etc.

A mile would be a better estimate of the typical range extension, beaming at an aperture of 45 degrees wide.

Thousands of TurboTenna 11N PRO cAntennae have been sold worldwide and it has quickly become a field proven product to increase the range of (or discover) Wi-Fi networks, and most recently, to extend the range of a drone controller for such as a camera quadcopter.

To connect the TurboTenna 11N PRO cAntenna to the Wi-Fi adapter, wireless router and drone controller is simple, what you need is an Ultra Low-Loss matching RF cable typically at 6 feet long with the RP-SMA connector (on the right).

Performance = Gain + Visibility

The isotropic gain of an antenna is expressed in dBi. 3dBi is x2; 6dBi is x4; 9dBi is x8; 12dBi is x15.8; 15dBi is x31.6 and 18dBi is x63.2 and so on.

The aperture (visibility) of an antenna simply gets narrower as the gain becomes higher.

An optimal point strikes when performance meets visibility.

The TurboTenna 11N PRO cAntenna is designed with an ultimate balance of gain and visibility which allows you to "see" more Wi-Fi signals with high penetration power for hotspot access and Wardriving.

Aee also dBi versus dBm.

Many years ago, wardriving was commonly referred to driving around looking for hotspots and wireless networks. Wi-Fi enthusiasts could pick up distant unsecured signals using the TurboTenna 11N PRO cAntenna and get on the FREE RIDE of Internet access.

Although this practice is controversial, it is not recommended unless a consent is obtained from the Wi-Fi owner.

Most recently, many buyers are coming to us for solutions to fill the blind spots of their home networks. What they found out was that the speed of the Internet is dependent upon the signal strength. A weak Wi-Fi connection results in choppy video when the HD/4K Smart TV and the wireless router are in the opposite sides of the living room and sometime blocked by walls also.

Interference will be a problem with too many residential Wi-Fi networks in your vicinity. Boosted signal quality not only avoids intermittent disconnection but also improves speed. It deteriorates with noises from overlapping channels, 2.4GHz cordless phones, TV wireless relay, baby monitoring devices and microwave ovens. The TurboTenna 11N PRO cAntenna screens such airwave pollution by beaming the sources to increase the signal-to-noise ratio.

But range extension is not the only purpose, professional network security auditors are using the TurboTenna 11N PRO cAntenna to test the outer boundaries of the wireless LAN, and to map the contours of signal coverage. Teachers use it to demonstrate the physics of resonant standing waves. The geeks put a satellite dish against it as a reflector and use it for signal relay.
