Antenna preamplifier Johansson KIT 7473L2 Smart Amp

Product detailed description

Antenna preamplifier Johansson KIT 7473L2 Smart Amp
The Johansson Smart Amp for DVB-T2 and DAB+ radio automatically searches and processes the incoming signal so that all output channels are matched to the same signal level. If an identical channel is received from multiple directions, it will be converted to the next frequency and not lost, unlike simple combiners. Allows up to 3 separate antennas to be merged. The output signal is also freed from unwanted interference by the 5G LTE filter. The high strength and weatherproof housing allows for both outdoor and indoor installation. Included is a 12V power supply with two outputs for easy powering of an additional antenna lead. Thanks to Plug and Play there is nothing to configure, just plug everything in, making the merging of several antennas as easy and convenient as possible.
