The amplifier boosts the received signal by 16 dB, raising the effective gain of the antenna-plus-amplifier system to 22.5 dB, making it suitable for locations where passive antennas deliver marginal signal levels.\u003c\/p\u003e\u003cp\u003ePower for the built-in amplifier is supplied through the same coaxial cable as the reception signal — either from an external power supply or directly from a DVB-T receiver that supports antenna power. The amplifier requires power to operate; the antenna does not receive signals in passive mode.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e20-element UHF logarithmic aluminium antenna, 440 mm length\u003c\/li\u003e\n\u003cli\u003eFull UHF coverage: CH 21–69, 470–862 MHz\u003c\/li\u003e\n\u003cli\u003eBuilt-in DIGI-LOG 14VU amplifier with 16 dB amplification\u003c\/li\u003e\n\u003cli\u003eCombined antenna gain: 22.5 dB\u003c\/li\u003e\n\u003cli\u003eAmplifier noise figure: 2 dB\u003c\/li\u003e\n\u003cli\u003ePower supplied through the coaxial cable at 5–24 VDC, 25 mA (optional external supply or via DVB-T receiver)\u003c\/li\u003e\n\u003cli\u003eIntegrated F female connector\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Benefits\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e22.5 dB total gain substantially improves reception in weak-signal locations where a passive antenna alone is insufficient\u003c\/li\u003e\n\u003cli\u003ePower-over-coax supply eliminates the need to run a separate power cable to the antenna location\u003c\/li\u003e\n\u003cli\u003e2 dB noise figure on the amplifier keeps added noise low, preserving signal quality rather than simply amplifying noise along with the signal\u003c\/li\u003e\n\u003cli\u003eFront-to-back ratio of 20–30 dB reduces interference from signals arriving behind the antenna\u003c\/li\u003e\n\u003cli\u003eAluminium construction keeps the unit lightweight at 440 mm length, simplifying outdoor mounting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency Range (Antenna):\u003c\/strong\u003e CH 21–69, 470–862 MHz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBand:\u003c\/strong\u003e UHF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImpedance:\u003c\/strong\u003e 75 Ohm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Elements:\u003c\/strong\u003e 20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAntenna Gain:\u003c\/strong\u003e 22.5 dB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFront-to-Back Ratio:\u003c\/strong\u003e 20–30 dB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 440 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Aluminium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eF Connector:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmplifier Model:\u003c\/strong\u003e DIGI-LOG 14VU\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmplifier Frequency Range:\u003c\/strong\u003e Ch.5–69 (174–862 MHz)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmplification:\u003c\/strong\u003e 16 dB @ 5–24 VDC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNoise Figure:\u003c\/strong\u003e 2 dB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Supply:\u003c\/strong\u003e 25 mA @ 5–24 VDC (via coaxial cable; external supply or DVB-T receiver — optional)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmplifier Connector:\u003c\/strong\u003e F female\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eWhy You'll Love It\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eA single compact unit combines antenna and amplifier, reducing the number of components installed outdoors\u003c\/li\u003e\n\u003cli\u003ePower delivered through the coaxial cable means no separate mains connection at the antenna position\u003c\/li\u003e\n\u003cli\u003eCompatible with external power supplies or DVB-T receivers that deliver power over the antenna cable\u003c\/li\u003e\n\u003cli\u003e22.5 dB combined gain opens up reception in fringe areas that standard passive outdoor antennas cannot serve\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Iskra","offers":[{"title":"Default Title","offer_id":56518969262462,"sku":"202113","price":22.89,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0961\/2250\/3550\/files\/15658953015678.webp?v=1779626546","url":"https:\/\/lynk.gr\/en-eu\/products\/iskra-p20f-dtt-g","provider":"Lynk.gr","version":"1.0","type":"link"}
