Each input has independent gain adjustment, allowing precise optimisation of each signal path in a single head-end unit.\u003c\/p\u003e\u003cp\u003eThe amplifier is fully LTE-ready and RED compliant (selectivity classifications 0 and 1). It includes switchable VDC remote power, a detachable power supply, and a -30 dB test output. The UHF1 and UHF2 inputs can be switched between 470–694 MHz and 470–862 MHz to accommodate different regional frequency plans or LTE filter requirements.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5 inputs: BI\/FM (47–108 MHz), BIII\/DAB (174–240 MHz), UHF1 (470–694 or 862 MHz, switchable), UHF2 (470–694 or 862 MHz, switchable), SAT (950–2400 MHz)\u003c\/li\u003e\n\u003cli\u003e1 main output + 1 test port (-30 dB)\u003c\/li\u003e\n\u003cli\u003eSplit-band amplifier with interstage attenuators and 20 dB dynamic range per input\u003c\/li\u003e\n\u003cli\u003eSwitchable VDC remote power: OFF – 12V – 24V\u003c\/li\u003e\n\u003cli\u003eSAT DC mode: OFF – 13V – 18V – 22 kHz (selection: internal, power inserter, or external)\u003c\/li\u003e\n\u003cli\u003eRED compliant — selectivity classifications 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\u003eFive separate inputs with independent gain control allow each band to be individually optimised within one compact unit, eliminating the need for separate per-band amplifiers\u003c\/li\u003e\n\u003cli\u003eSwitchable UHF frequency range (694 or 862 MHz upper limit) adapts the amplifier to national frequency plans with built-in LTE interference rejection\u003c\/li\u003e\n\u003cli\u003eVDC switchable remote power supplies antenna pre-amplifiers or masthead amplifiers directly through the coaxial cable\u003c\/li\u003e\n\u003cli\u003eSAT DC mode supports LNB powering with 13V\/18V switching and 22 kHz tone for satellite band\/polarity selection\u003c\/li\u003e\n\u003cli\u003eRED compliance ensures the amplifier meets EU radio equipment directive requirements\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInputs:\u003c\/strong\u003e 5 (BI\/FM, BIII\/DAB, UHF1, UHF2, SAT)\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 — BI\/FM:\u003c\/strong\u003e 47–108 MHz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency Range — BIII\/DAB:\u003c\/strong\u003e 174–240 MHz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency Range — UHF1:\u003c\/strong\u003e 470–694 or 862 MHz (switchable)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency Range — UHF2:\u003c\/strong\u003e 470–694 or 862 MHz (switchable)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency Range — SAT:\u003c\/strong\u003e 950–2400 MHz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGain — BI\/FM:\u003c\/strong\u003e 10–30 dB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGain — BIII\/DAB:\u003c\/strong\u003e 10–30 dB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGain — UHF1:\u003c\/strong\u003e 15–35 dB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGain — UHF2:\u003c\/strong\u003e 15–35 dB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGain — SAT:\u003c\/strong\u003e 10–35 dB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSlope Adjustment — SAT:\u003c\/strong\u003e 0–10 dB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax.
