Amplifier kit SMART 3 inputs + FA LTE2 (5G) Johansson

It has never been easier to combine 2, 3 or 4 antennas for the reception of full HDTV signals. The combination of several terrestrial antennas to receive full HDTV signals in single family homes (SFU) is often a problem. Most of the time, the signal from several antennas is combined using a simple distributor, but this solution does not work.

  • 4 dB (minimum) losses = we only have half the signal when 2 antennas are combined
  • Channels on the same frequency are lost
  • Low isolation between adjacent channels
  • Many interruptions due to poor signal quality

Viewers tend more and more towards terrestrial TV reception. But the current situation is not at all optimal ... Therefore, the market needs a solution that offers:

  • Better signal quality
  • More channels
  • Plug & Play installation (no configuration required)

Mast amplifier SMART AMP 3 inputs LTE2 (7473L2)

  • The Smart Amp performs an automatic search of all channels, amplifies weak signals while keeping channels strong
  • All output channels have uniform and stable power
  • Handles even the most difficult situations with adjacent channels

  • Automatic recognition of the country's channel plan
  • SAW filters for LTE-5G protection on all inputs
  • Weather-resistant outer shell for pole mounting
  • DC power via coaxial cable
  • All ports protected against electrostatic discharge
  • Meets RED CE standard
  • Output level: 85dB

2-outlet power supply (2437)

  • High efficiency power supply
  • Stabilized 12Vdc / 400mA
  • Short circuit protection
  • Power LED indicator
  • Wall or DIN rail mounting
