MEET THE NEW JOHANSSON SMART AMPLIFIER!
Connecting 2 or 3 TV antennas for the best signal reception - IT'S NEVER BEEN SO EASY
Combining multiple terrestrial antennas for full HDTV reception is often a problem.
Usually, the signal from many antennas is connected using a simple splitter, crossover, but this solution does not work well:
- Signal loss 4dB (minimum) = only half of the signal remains when two antennas are connected
- Channels with the same channel number are lost
- Poor insulation between adjacent channels
- Many interruptions, interference caused by poor signal quality
Viewers are increasingly paying attention to the reception of terrestrial television. 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!
Connecting multiple terrestrial TV antennas using a simple crossover (antenna adder) causes a lot of problems.
Channels with the same number and frequency values are lost. Neighboring channels are poorly isolated and poor signal quality causes many interruptions, video interference.
Johansson Smart Amp solves these problems!
It is a fully automatic active amplifier for digital terrestrial television.
This small amplifier offers the best signal quality and access to more TV content because it repositions the channels at the same frequency.
It diplexes adjacent channels and automatically maintains real-time gain controls.
This smart amplifier automatically scans all available channels, offers 360-degree TV signal reception.
Compatible with all terrestrial TV standards, built-in 4G and 5G LTE filters.
Installation is very simple: internal and external installation thanks to a special mast housing.
Possibility to connect up to four terrestrial antennas to an existing coaxial system.
Intelligent amplifier powered from an external ref power supply. 2437
Child's :) - connect the amplifier to the 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?
