Russian to know not necessarily. In the instruction all is drawn on pictures. The amplifier is included when connect the stabilizer in an electric network 220V.
How many kilometers up to TV of the transmitter?
On what frequency it is transferred DVB-T2 MUX 1?
What receiver DVB-T2 use, or the TV with DVB-T2?
I think dacha is roughly 40 Km far away the transmitter.
MUX 1 is on CH25
I use a D-COLOR decoder
Thanks again a lot for support
GRAZIE

The stabilizer does not work as the amplifier. The stabilizer submits U=12V. The amplifier is located in a black plastic box on the aerial. You correctly connect the stabilizer? The instruction for connection I send on e-mail.
Now all is clear, thanks a lot.
I think that I made all connection right because then I receive MUX 2 on CH39 and I can see its programmes.
Unfortunatly what is important for my mother in law is MUX 1 on CH25 (she want Perviy, Rossiya and NTV) and this is not received with enough power.
Antenna gain on CH25 is less than on CH39 so that maybe it is the reason I cannot see the programmes on that mux.
Change with H81/4 or H81/7 I think benefit on CH25 will be minimum whatching gain diagram.
Next year I shall try to put the antenna on an higher position and better steer it

Hello, what is the gain of delta h181a.01 antenna?
9.5 – 12 dB or 19.5-22 dB?
How can I get 19.5-22 dB gain?
What is the difference between h181 and h181a.01? Only stabilizator block?


H181 - the passive aerial. Amplification(strengthening) 8,5-11 dB.
H181A.01 - the active aerial. Amplification(strengthening) 29,5-32 dB.

Spasibo
H181A.01 is the one with stabilizator block right? Is it working also as amplifier? Where is the amplifier?
If I connect or not the stabilizator (I think is the translation of blok pitaniya) the result is always the same.
What I am doing wrong?
I hope you can help me. Trying to receive DVB-T2 MUX 1...
