It accepts four distinct frequency bands simultaneously — BI\/FM, BIII\/DAB, and two independently switchable UHF inputs — each with its own gain adjustment ranging 10–35 dB. A detachable external power supply is included.\u003c\/p\u003e\u003cp\u003eThe amplifier is RED compliant and fully LTE-ready, with switchable UHF band limiting at 694 MHz or 862 MHz. A dedicated –30 dB test output allows signal monitoring without interrupting the main distribution chain. VDC remote power is selectable at OFF, 12 V or 24 V for powering downstream LNBs or masthead amplifiers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4 inputs: BI\/FM (47–108 MHz), BIII\/DAB (174–240 MHz), UHF1 and UHF2 (470–694 or 862 MHz, switchable)\u003c\/li\u003e\n\u003cli\u003eSplit-band design with interstage attenuators and 20 dB dynamic range per band\u003c\/li\u003e\n\u003cli\u003eSeparate gain adjustment per input: 10–30 dB for BI\/FM and BIII\/DAB; 15–35 dB for UHF1\/UHF2\u003c\/li\u003e\n\u003cli\u003eSwitchable LTE filter (694 or 862 MHz cut-off)\u003c\/li\u003e\n\u003cli\u003e–30 dB monitoring test port\u003c\/li\u003e\n\u003cli\u003eVDC remote power: OFF \/ 12 V \/ 24 V switchable\u003c\/li\u003e\n\u003cli\u003eRED compliant (selectivity classes 0 and 1)\u003c\/li\u003e\n\u003cli\u003eDetachable power supply included\u003c\/li\u003e\n\u003cli\u003eCompact housing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Benefits\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eIndependent gain controls per band prevent strong signals on one input from degrading others\u003c\/li\u003e\n\u003cli\u003eHigh input power threshold makes input overload virtually impossible in demanding installations\u003c\/li\u003e\n\u003cli\u003eLTE filter switching lets the installer adapt to local spectrum allocation without hardware changes\u003c\/li\u003e\n\u003cli\u003eRemote power output eliminates the need for a separate power supply at a masthead unit\u003c\/li\u003e\n\u003cli\u003eThe test port enables level checking during commissioning without disconnecting any cables\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e Johansson 7784\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInputs:\u003c\/strong\u003e 4 (BI\/FM, BIII\/DAB, UHF1, UHF2)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutputs:\u003c\/strong\u003e 1 main + 1 test port (–30 dB)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency range:\u003c\/strong\u003e BI\/FM: 47–108 MHz; BIII\/DAB: 174–240 MHz; UHF1: 470–694 or 862 MHz (switchable); UHF2: 470–694 or 862 MHz (switchable)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGain (dB):\u003c\/strong\u003e BI\/FM: 10–30; BIII\/DAB: 10–30; UHF1: 15–35; UHF2: 15–35\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax. input power (dBµV, –60 dBc):\u003c\/strong\u003e BI\/FM: 94; BIII\/DAB: 92; UHF1: 96; UHF2: 96\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax. output power (dBµV, –60 dBc):\u003c\/strong\u003e BI\/FM: 118; BIII\/DAB: 119; UHF1: 118; UHF2: 118\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNoise figure (dB):\u003c\/strong\u003e BI\/FM: 4.5; BIII\/DAB: 4; UHF1: 5.5; UHF2: 5.5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReturn loss (dB):\u003c\/strong\u003e \u0026gt;10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTest port (dB):\u003c\/strong\u003e –30\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRemote power (V):\u003c\/strong\u003e OFF – 12 V – 24 V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDC mode (mA):\u003c\/strong\u003e BIII\/DAB: 100; UHF1: 100; UHF2: 100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRED selectivity classification:\u003c\/strong\u003e 0 and 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupply voltage (VAC):\u003c\/strong\u003e 100–240\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower consumption (W):\u003c\/strong\u003e 23\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIn the box:\u003c\/strong\u003e 1 x Johansson 7784 amplifier, 1 x power adapter cord, 1 x instruction manual\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eWhy You'll Love It\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMore efficient than its predecessor — same rack space, better performance\u003c\/li\u003e\n\u003cli\u003eCompact housing fits neatly into an existing head-end cabinet\u003c\/li\u003e\n\u003cli\u003eAll signal levels are independently tunable, so the output is balanced for every outlet in the building\u003c\/li\u003e\n\u003cli\u003eFull LTE readiness future-proofs the installation against spectrum refarming\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Johansson","offers":[{"title":"Default Title","offer_id":56564268728702,"sku":"203320","price":223.0,"currency_code":"NZD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0961\/2250\/3550\/files\/15671552049534.webp?v=1779614900","url":"https:\/\/lynk.gr\/en-nz\/products\/johansson-7784-multiband-amplifier-4-inputs","provider":"Lynk.gr","version":"1.0","type":"link"}
