Televes NanoKom T561821 mastovahvistin

The Televes T561821 is a new generation of masthead amplifier. Set the output level you want and the amplifier's AGC feature will keep it right where you want it.TV picture interference is almost always caused by a signal that is too weak. If the signal from your TV aerial is less than 45 dB, you need a mast or aerial amplifier. For aerial reception, the signal usually needs to be amplified to provide a strong enough (45-74 dB) connection to all aerial frames. An amplifier is particularly useful when receiving a picture from a TV transmitter station at a distance.Televes NanoKom masthead amplifier (LTE700) 3 inputs: BIII-UHF-FMmix.
