What are the influences to receive a good digital TV signal from the easyDVBT?

Let us explain what influences good reception.

  1. How does the unit work: Normally a VHF antenna do not receive well the UHF frequencies of the television transmitters. But there is still a reception signal, even with the regular VHF antenna. What the easyDVBT does is, that it amplifies the UHF television signal so that the digital receiver can work with the signals. But to do so, it is necessary to get an “even small” UHF signal to the unit, to amplify it there.
  2. UHF attenuation of cables. The regular used VHF cables are of the type RG58. These cables do have a normal attenuation at the VHF frequencies of app. 140-160Mhz. But at the UHF frequencies for TV, up to 900 MHz the attenuation of these regular cables is very high, which means very poor signal transmission of these frequencies. Just to give you an idea: RG58 at 144MHz for 10 m cable: attenuation app. -1.9 dB RG58 at 900MHz for 10 m cable: attenuation app. -6,5 dB
  3. Poor transmission power of TV stations In some areas the coverage and the transmission power is not very good. This means that almost no signal is received.

Summary: To recveive a good TV signal out of the easyDVBT you need a good cabling, e.g. RG213 or Aircell 7 or Ecoflex 15 and good cable connections from the cable to the unit. Also the area where you are sailing is important, that there is enough “signal strength” to reveive TV signals.
