MEET THE NEW JOHANSSON SMART AMPLIFIER!
Amplifying the signal of TV antennas for the best signal reception - NEVER WAS THIS SIMPLE
Viewers are increasingly paying attention to terrestrial TV reception. But the current situation is absolutely not optimal....
The market needs a solution that will offer better signal quality, more TV channels, plug & play installation!
The combination of multiple terrestrial TV antennas using a simple crossover (antenna combiner) causes many problems.
Channels with the same number values and frequencies are lost. Adjacent channels are poorly isolated and poor signal quality causes many interruptions, video interference.
Johansson Smart Amp solves these problems!
This is a fully automatic active amplifier for digital terrestrial TV.
This small amplifier offers the best signal quality and access to more TV content as it repositions channels with the same frequency.
Multiplexes adjacent channels and maintains real-time gain controls automatically.
This smart amplifier automatically scans all available channels, offers 360-degree TV reception.
Compatible with all terrestrial TV standards, built-in 4G and 5G LTE filters.
Installation is very easy: indoor as well as outdoor installation thanks to a special mast housing.
Can connect up to four terrestrial antennas to an existing coaxial installation.
Smart amplifier powered by an external power supply ref. 2437
Child's play installation :) -connect the amplifier to your antenna system and the AUTOSCAN function will do the rest for you.
So, do you want to receive more terrestrial TV channels with better signal quality?
