What antenna is needed?
Also necessary antenna that will receive digital signals in the 470-860 MHz band. It can be two versions: indoor to place her indoors or external. The use of room antenna is assumed if the tower of a television repeater is located within 15 kilometers, otherwise the optimal solution will be the use of external.

Digital Broadcasting Standard
Television format is determined by the source of broadcasting.
- DVB-C. The format of ordinary television, which provides a specific provider.
- DVB-S2, DVB-S. TV signal reception is carried out through a satellite on a plate. As a result, the resulting impulse is converted into a decoder, due to which the video relay is able to organize a telephoneial relay.
- DVB-T. The signal receives a decimeter antenna by using a radio-pool channel.
- DVB-T2. Improved reception option and DVB-T conversion. High quality image in HD and 3D-format, nice sound and video.

You will have to choose the prefix for a long time and carefully not to miss the useful tuner property useful for you. Or not to pay unnecessary for its functions that you do not need.
It is very important that the prefix to digital television almost will not improve and will not worsen the reception of the digital television signal. All tuners are similar in their characteristics. First of all, the operational parameters of the console. Enough so that the tuner is optimized for working with television signal in DVB-T2 standard.All other functions of the receiver. at your request. The more expensive the prefix. the more functions.
On the forums, questions are often discussed on the topic, which of the tuners it takes better, and what worse. Let discuss! With a sufficient antenna signal, all tuners show normally. With a weak signal, there are cases when “one tuner also shows, and the other is no longer”. In such a situation, it is better to immediately do an antenna, and not a choice which of the tuners is a little more sensitive.
Some consoles are managed only from the remote. The presence of buttons on the device itself is a positive moment when the console is selected.
There is an inconvenience that while watching TV, the viewer is at once two consoles, from tuner and from the TV. The television console must be turned on and off the TV, and from the remote control of the tuner to switch the channels and change the volume.
TV viewers who are very like comfort buy universal consoles with the function of their “learning”. Such a remote control can be simultaneously driving and tv and tuner. Such a remote can be trained so that only the transition buttons across the channels, volume and shutdowns in order to accidentally not click “something not that”.
