Antenna preamplifier smart JOHANSSON KIT 7472L2 Smart Amp

Product detailed description

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. It allows you to wisely merge 2 separate antennas. The output signal is also free from unwanted interference by using a 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 the plug and play standard there is nothing to configure, just plug everything in, making the merging of several antennas as easy and convenient as possible.
