DVB DVB-T DTT antenna coupler for cars

With the exception of some mid-to-high-end models, most DVB decoders are equipped with only two antenna inputs.
Precisely because the car can move in the direction of the TV repeater or in the opposite direction, the antennas are positioned front and rear of the car but since the car can orient itself in several directions it goes without saying that this arrangement in some cases appears insuffcient.
To ensure 360-degree coverage and therefore the possibility of receiving the TV signal regardless of the direction of the car, it is ideal to insert four antennas, one for each corner of the car.
