TV - Receiver Dynamic Range
Most TV / DVB-T Receivers have a signal range of -65 to -5dBm.
This also corresponds to bars (signal strength bars) which display on a receiver.

Passive Splitters
On passive splitters there is a signal loss that occurs depending on many ways the signal is being split. So it is important to be aware of this, as this may cause enough signal loss to reduce the signal at the TV. |
Signal Loss
Both outputs connecting into passive or active splitter will create a more balanced system as the increased 10dBm is not necessary
There is 10dbm attenuation (signal loss) when 2 devices are looped. Power needs to be increased to compensate, see Configuration 1
