The Antenna play’s a vital role in the performance of wireless gateway’s installed in vehicles

To maximise the performance of vehicle wireless routers it is essential that you install the correct type of antenna.

The key points to consider are:

Mounting Position. A panel mounted antenna is always going to out perform any other type  of antenna but this is not allways practical to install in some vehicles so other options include internal antennas that fit on the vehicles windscreen or dashboard or magnetic mount antennas.



Fits Internally.  Cellular, Wifi, GPS/GNSS Telematics Antenna. Fits securely on the windscreen or dash using acrylic adhesive. Very easy to install.

External panel/roof mount. GPS/GNSS, MiMo 4G/3G/2G & Optional MiMo 2.4/4.9-6GHz.



Mini Magnetic Mount Wifi Antenna (SMA).Wireless LAN 2400-2485 MHz


Network compatibility. Most IoT applications work on a combination of Cellular LTE, WiFi and other WLAN technologies like Bluetooth and Zigbee and LPWAN (LoRaWAN, NB-IoT, Sigfox) and GPS, GNSS for location. Wireless networks use a dedicated frequency range which the antenna needs to cover.

Cable. To optimise the antennas performace it’s best to minimise the length of cable used as long lenghths of cable can result in signal loss. It’s essential that any cable extenisons used are low loss RG58 coax for the cellular part of the router and double shielded dielectic coax which offers excellent performance up to 6GHz for the WiFi application on the router. Co-Star can manufacture RG58 cable extensions with any combination of connector and cable length. Click here for more information> 

Connectors. The most common connector used on wireless Gateway’s is the SMA series. A standard SMA male is normally used for the cellular application and a reverse polarity SMA male is used for the WiFi application. Some manufacturers of wireless devices do use alternative connectors, to help you choose the correct connector please click on the following  link co-star-connector-matrix.
