Your local TV stations may provide free over the air ATSC-M/H service for mobile receivers, but each time you watch them on your cell phone or tablet you pay the phone company unnecessary fee. You can avoid this fee by receiving the free programs directly through this mobile TV receiver.

100% performance guarantee if connected via required ATSC-M/H signal. Please contact your local TV stations to validate the ATSC-M/H service.

(Disclaimer: The existence of ATSC-M/H service in any specific given region is in the hands of the local broadcasters. is not responsible for the availability of such service.)


The DMT9.4 is a state-of-the-art Digital TV Tuner for car application. It is complient with USA ATSC-M/H standard for mobile vehicles, enabling you to enjoy your favorite TV program while on the move or stationed. With this unique car TV tuner, you can view the major TV channels (where ATSC-M/H service is available) by simply connecting the TV tuner to your current mobile video system. Using additional small (optional) device you can send your favorite programs to your Notebook, Tablet or iPhone.

The DMT9.4 is not a simple terrestrial receiver. It has a powerful Doppler Effect* (See explanation below) correcting feature to prevent lose of TV signal in moving cars. This problem is typical to many car TV tuners. Consequently these "regular" terrestrial ATSC tuners can be used only when the car is stopped. On the other hand: the DMT9.4 deliver excellent digital pictures while the car is moving. The correction mechanism is effective in car speed of over 230 km/h (143 mph, about 125 Knots).

Why this tuner?  Not every 12V low priced tuner is a real "Car TV Tuner": Most of them have a "regular" ATSC tuner and will work only while the car is stopped. There will be no reception as the car starts moving again because the tuner is not ATSC-M/H compliant.

* What is Doppler Effect?

The Doppler effect (or Doppler shift), named after Austrian physicist Christian Doppler who proposed it in 1842 in Prague, is the change in frequency of a wave for an observer moving relative to the source of the wave. It is commonly heard when a vehicle sounding a siren or horn approaches, passes, and recedes from an observer. The received frequency is higher (compared to the emitted frequency) during the approach, it is identical at the instant of passing by, and it is lower during the recession.

Where To Use? - In Cars, RVs, Trucks, Motorbikes, Trains, Boats...
