{"product_id":"antenni-predzesilovac-inteligentni-johansson-kit-7472l2-smart-amp","title":"Intelligent antenna preamplifier JOHANSSON KIT 7472L2 Smart Amp","description":"The intelligent preamplifier for DVB-T2 and DAB+ radio Johansson Smart Amp automatically searches for 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 directions, it is converted to the next frequency and not lost, unlike simple combiners. It allows you to cleverly combine 2 separate antennas. The output signal is also free from unwanted interference using a 5G LTE filter. The housing with high strength and weather resistance allows for installation outdoors and indoors. The package includes a 12V power supply with two outputs for easy powering of an additional antenna lead. Thanks to the Plug and Play standard, there is no need to configure anything, just connect everything, making combining multiple antennas extremely easy and convenient.\u003cbr\/\u003e\u003cbr\/\u003eProduct features\u003cbr\/\u003e- convenient and smart merging of 2 antennas\u003cbr\/\u003e- designed for DVB-T2 and DAB+ radio broadcast\u003cbr\/\u003e- automatic adjustment of all channels to the same level (AGC)\u003cbr\/\u003e- peak filter slope for adjusting adjacent channels\u003cbr\/\u003e- automatic detection of SAW filters\u003cbr\/\u003e- integrated 5G LTE filter\u003cbr\/\u003e- protection against electrostatic discharge (ESD)\u003cbr\/\u003e- power supply and mounting hardware included\u003cbr\/\u003e- for indoor and outdoor use\u003cbr\/\u003e- Plug and Play standard, nothing needs to be configured\u003cbr\/\u003e- F connectors\u003cbr\/\u003e\u003cbr\/\u003eTechnical parameters\u003cbr\/\u003e- number of inputs: 2\u003cbr\/\u003e- number of outputs: 1\u003cbr\/\u003e- active band: DAB+ \/ VHF (BIII), UHF k. 21 - 48\u003cbr\/\u003e- operating frequency: 174 - 240 MHz \/ 470 - 694 MHz\u003cbr\/\u003e- input level: 40 - 100 dBµV\u003cbr\/\u003e- output level: 90 dBµV - AGC\u003cbr\/\u003e- isolation between inputs: \u003e 35 dB\u003cbr\/\u003e- LTE band suppression: \u003e 40 dB\u003cbr\/\u003e- power supply (2437): 12V DC, 350 mA (max.)\u003cbr\/\u003e- input voltage of the power supply: 230V~AC, 50 Hz\u003cbr\/\u003e- number of power supply outputs of the power supply: 2 (F connector)\u003cbr\/\u003e- preamplifier dimensions: 112 x 98 x 56 mm\u003cbr\/\u003e- power supply dimensions: 120 x 115 x 50 mm\u003cbr\/\u003e\u003cbr\/\u003ePackage contents\u003cbr\/\u003e- 1x Johansson 7474L2 preamplifier\u003cbr\/\u003e- 1x 2437 power supply\u003cbr\/\u003e- 1x mast case\u003cbr\/\u003e- 1x manual","brand":"JOHANSSON","offers":[{"title":"Default Title","offer_id":53047469343058,"sku":"14430916","price":2850.0,"currency_code":"CZK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0954\/9624\/1490\/files\/14430916_26f7965f-865d-4a97-8111-4afdd639e682.png?v=1776148829","url":"https:\/\/tipa-production.myshopify.com\/en\/products\/antenni-predzesilovac-inteligentni-johansson-kit-7472l2-smart-amp","provider":"TIPA","version":"1.0","type":"link"}
