Boost your signal strength with a GPS or TMC antenna from subtel®

Do you find yourself driving in areas with poor internet coverage, causing your GPS or Sat Nav device to lose connection and provide you with inaccurate routes and navigation?

Ensure you’re always following the correct route with a booster GPS antenna or TMC antenna (Traffic Message Channel antenna).

These antennas work by amplifying the signal received by your car's radio or GPS receiver - ensuring a much improved, reliable signal. Small but powerful, you can significantly boost the signal strength you receive - even in areas off the grid.

What is a TMC antenna?

Traffic Message Channel (TMC) is a messaging system that transmits traffic status updates and information in coded form, using a radio signal, to systems capable of decoding it, such as GPS navigators and many car stereos such as smart car stereos with in-built Sat Nav functionality.

The messages received via TMC informs us of incidents such as traffic jams, accidents, weather or road conditions that may affect our route whilst driving. Using this information, navigation systems can recalculate routes to find the fastest possible journey, avoiding any major problems flagged by TMC.

A TMC antenna boosts the reception of your TMC-capable device, enabling you to receive accurate, detailed information about your route, even in areas of poor internet coverage such as in rural areas or mountainous terrain.

These small antennas simply plug into your TMC-enabled devices such as GPS devices and act as a radio mast, amplifying the signal strength your device receives.

What is a Sat Nav / GPS antenna?

Global Positioning System (GPS) antennas allow tracking and tracing applications to access GPS/GNSS (Global Navigation Satellite System) satellites. Their function is to pick up the L-band signals transmitted from these satellites and transfer them to a processing device to determine the exact location of that device on the planet.

GPS devices usually have internal antennas for receiving this data. While these internal antennas perform generally well in areas with good signal strength, they can struggled to receive accurate information in rural or mountainous areas or areas with poor signal strength.

External GPS antennas boost the strength of the signal received by your GPS device. Once plugged into your device, they’ll begin to pick up more information than your internal antenna alone, giving you an accurate, complete picture of your surroundings and route.

subtel®’s online shop sells a wide range of high-quality GPS antennas for car, GPS ariels, Sat Nav antennas and TMC antennas for a large number of brands such as TomTom, Navigon, Blaupunkt, Garmin, Navman and many more - with a 3-year warranty on every antenna.

Which external antenna is right for my GPS?

Different GPS and TMC antennas fit to different GPS devices. Some use different plugs and sockets and others simply different technology.

For each TMC antenna, GPS and Sat Nav antenna we sell, we provide a list of 100% compatible GPS devices to ensure you never buy the wrong product.

This list can be found every time you click on a GPS or TMC antenna on our webshop. Simply scroll to the bottom of the product page and you’ll find this compatibilities list. If your GPS brand and model is within that list, the antenna is correct for your device.

Reliable navigation when you need it

Our external GPS and TMC antennas are all you need to keep on the right track on long journeys - even when you’re off the grid.

All antennas are shipped within the UK from the day your purchase is made and come with a 3-year manufacturer’s warranty.

If for whatever reason you’re unsatisfied with the quality of our product, you can return it within 30 days.
