TNT issue displays "no signal"

Hello everyone
to avoid struggling with a black screen, you first need to ensure you have an excellent antenna signal. Digital reception does not recognize "close enough," and there will never be any snowy images; below a certain signal level, a black screen is guaranteed.
To give yourself the best chance, read the installation tips on www.tvnt.net and www.telesatellite.com (terrestrial DTT section)
Good luck

Hello, take your set-top box and plug it in place of the working one in the living room, then search for your channels and plug it into the other room. If it doesn’t work, then there’s a problem with the set-top box, not bad, huh!!!

Attention "Furtif" to bad advice, a decoupler amplifier does not exist. Regarding the 3 dB loss after each connection, that's incorrect; we lose 0.5 dB. However, we lose 4.5 dB after a split into 2 paths. Therefore, after 3 connections, one shouldn't claim there is no signal left. A distribution amplifier is unnecessary (2 paths) in a very strong field because there is a reserve of signal.
