To optimize DVB-T2 waves, the first step is to determine the location of the DVB-T2 base station.

Once the position of the DVB-T2 transmitter is correctly defined, you can use the Google map to find the direction of the receiving antenna and see how far the distance from the transmitter to the antenna is to select the antenna location so that best fit. Besides the distance and antenna direction, other important factors for DVB-T2 wave reception are the transmit power, antenna height and obstacles between the transmitting antenna and the receiving antenna.

If you are living near the station (about a few kilometers away) and have few wave obstructions, simply set the DVB-T2 antenna in the home to receive DVB-T2 waves well. Conversely, when further away, where there are more obstacles, you must select and install the antenna at a high position to receive DVB-T2 waves.

3. Select the antenna connection with the receiver

Choosing antenna cables is one of the important jobs. It is known that coaxial cable has anti-interference ability as well as higher durability than parallel cable, so there is no reason why you do not use coaxial and good jack in all cases. The fact also shows that the spiral connector with coaxial cable is easy to install without the need for specialized tools. And yet, they also have good water resistance and very solid.

Some notes about antenna wires :

1. Choose high quality coaxial cable.
2. Try not to wire and bend the rope.
3. Outdoor antennas require lightning protection ground to ensure more safety.
4. Apply silicone sealant around the joints or tape insulation to protect outdoor connections when exposed to weather elements.
