The real coverage

Description: 

The DTT coverage depends directly from the electromagnetic eld that covers certain area, but it also depends from the reception system and the receiver installed. The reception quality in a certain area between a DTT PEN receiver and a reception system with external UHF antenna can not be compared.
Therefore, the coverage in certain areas depends largely on the quality of reception and tuning system.
For areas of low or good coverage, the antenna DAT HD Boss, ref. 1495, automatically adjusts its signal output to a

 

 correct value for the DTT receiver.
Another factor that depends on receiving DTT or not, is the dynamic range of the receiver. The zAs HD ref. 5124, features an input dynamic range (range of levels from which the recipient can work) between 45 and 90 dBuV, assuring the DTT reception in pretty extreme conditions of signal level. Moreover, eld tests have demonstrated the possibility of receiving DTT with signicantly lower levels (see figure).

 

 In conclusion, in a certain area, it may be impossible to receive the DTT with certain receivers, while with others, it is possible. To determine whether there is really DTT coverage, try with a DAT HD Boss antenna and with a DTT zAS HD receiver according to the figure!.If in these conditions you can not receive DTT, then there is really no coverage in the área.
