Antenna intelligent preamplifier Johansson KIT 7473L2 Smart Amp
The Johansson Smart Amp intelligent preamplifier for DVB-T2 and DAB+ radio automatically scans and processes the incoming signal so that all output channels are aligned to the same signal level. If an identical channel is received from multiple antennas, it will be converted to the next frequency and not lost, unlike with simple combiners. It allows combining up to 3 separate antennas. The output signal is also free of unwanted interference using a 5G LTE filter. The housing with a high strength and resistance to weathering allows installation in the outdoor environment as well as indoors. The package includes a 12V power supply with two outputs for easy powering of another antenna lead. Thanks to the Plug and Play standard, there is no need to configure anything, which makes combining several antennas as easy and convenient as possible.
