Novotech has put together a list of the most frequently asked questions about Airgain Antennas. If you have additional questions, we encourage you to call one of our IoT experts to help you assess your project needs. 

 

First here’s a little background on Airgain: 

Airgains antennas are deployed in fleet, enterprise, private, government, and public safety wireless networks and systems.

In 2018, Airgain acquired Antenna Plus, an innovator of high-quality antenna products for mobile and automotive fleet applications for government, public safety, and Industrial IoT markets. The acquisition accelerated Airgain'sAirgain's penetration into several new and high growth markets, including mobile and automotive connectivity solutions for mission-critical applications, as well as outdoor antenna solutions for Industrial IoT applications. 

 

 

How do I know if my application needs an antenna?

All modems, routers and gateways with external antenna ports require an antenna. Airgain has a wide variety of antennas that support all your project needs. 

 

 

Can Airgain make custom cable lengths for my project? 

Yes, Airgain makes customizable cable lengths up to 35 feet. 

 

 

Can Airgain assemble custom connectors on my antenna?

Yes, Airgain can provide many different RF connectors, from SMA to Fakra – let us know what you need before ordering. 

 

 Some common choices are:

 

TNC: The TNC connector is a medium-sized form of RF connector. In overall form, it is very similar to the very popular BNC connector, but rather than having a bayonet connection, it uses a screw fit.

 

N-Type: N-Type connectors are designed to satisfy the need for a durable, weatherproof, medium-size RF connector with consistent performance through 11 GHz

 

SMA: SMA Connectors are 50 Ohm RF Coaxial connectors that operate up to 18 GHz. These connectors have a screw-type coupling mechanism that minimizes reflections and attenuation by ensuring uniform contact. SMA connectors are one of the most used RF connectors. They are used in a wide range of applications, including antenna connections for most sub 6 GHz technologies like Wi-Fi and Bluetooth.

 

Reverse Polarity Male and Female connectors: the ''center pin'' of the Male connector is swapped with the ''receptacle'' of the Female connector, i.e., a reverse polarity male connector has a receptacle at the interface instead of a center pin and reverse polarity female connector has a center pin at the interface.

 

SMA: The SMA connector is a 50-ohm coaxial connector. It is visually similar to an F type connector that is commonly used for audio/video communication but has different dimensions, mechanical properties and is used for various applications such as RF communications up to 18 GHz.

 

MCX: MCX (micro coaxial connector) are coaxial RF connectors developed in the 1980s. They have the same inner contact and insulator dimensions as the SMB connector but are 30% smaller. MCX is standardized in European CECC 22220

 

SMB: SMB connectors are coaxial RF connectors smaller than SMA connectors. They feature a snap-on coupling and are available in either 50 Ω or 75 Ω impedance. They offer excellent electrical performance from DC to 4 GHz.

 

Fakra: Fakra connectors meet the mechanical and environmental requirements of the automotive industry. The worldwide automotive industry has standardized on connectors based on the FAKRA and USCAR standards. They can be used to make various connections in automotive vehicles; applications include SDARS, Cellular, GPS Navigation, key-less entry and satellite radio.

 

 

How long will it take to receive my Airgain antenna?

If the antenna is not on the shelf at Novotech, standard lead times are 2-4 weeks. Airgain's lead times and flexibility consistently exceed customer expectations, making them a popular choice for our channel. 

 

Where are Airgain antennas manufactured?

Most of the Airgain Antennas are built in the USA. 

 

Airgain also maintains antenna design centers in North America, Asia Pacific, and Europe. This regional support provides flexibility to customize antennas specific to individual customer devices, maximizing design turnaround speed and, ultimately, device performance.

 

 

What type of mounting options are available?

Adhesive, Magnetic and Bolt options are available.

 

 

Is a ground plane required for nonmetallic surfaces?

Airgain Antenna Models, like the Ultramax B and the UltraMax MIMO B, features a built-in ground plane to accommodate installation on non-metal surfaces. The UltraMax Glass is ground Plane independent, so it's essential to assess your needs before purchasing. You can email our sales support at sales@novotech.com

 

 

What is the maximum cable length for stationary and mobile antennas?

The maximum cable length is customizable up to 35 feet. 

 

Does the surface need to be prepped for adhesive mount?

 

Yes. The surface temperature of the vehicle where the antenna will be mounted must be between 85°F to 100°F (30°C to 38°C). Airgain highly recommends using a heat gun to heat the surface and a laser temperature reading gun to measure the surface temperature to make sure it is adequately heated.

 

Step #1

Drill a 7/8" diameter hole where the center of the antenna will be located on the vehicle. 

 

Step #2

Clean the mounting surface with a provided alcohol wipe to remove dust, dirt, and oil. Allow the surface to dry. 

 

Step #3 

Pass antenna cables through the hole. Remove the backing on the bottom of the antenna exposing the adhesive pad.

 

Step #4 

Position the antenna and adhere it to the vehicle using firm hand pressure. 

 

 

Does the GPS cover GLONASS, Galileo, Beidou and other regional systems?

Yes, Airgain antennas that have GNSS support GPS L1/GALILEO E1/GLONASS G1/BeiDou B1/QZSS L1.

 

Can [omni-directional] antennas be mounted in any position, such as vertical, horizontal, etc.?

Antennas must be mounted horizontally - parallel to the ground (not mounted on a vertical surface).

 

How significant is "Gain" or high gain, and when is it needed?

An antenna's power gain or gain is a crucial performance number that combines the antenna's directivity and electrical efficiency. All Airgain antennas are Omni-directional and come with high gain.
