Its mechanical redesign provides enhanced gain and built-in 4G\/5G noise protection without requiring an active filter. High-quality materials ensure long-term outdoor mechanical resistance.\u003c\/p\u003e\u003cp\u003eThe P2845-7 is available in four variants: with or without F-connector, and in horizontal-only or horizontal\/vertical polarisation versions. This base variant (P2845-7) has no connector and is intended for horizontal polarisation only. It mounts on mast diameters of 20–50 mm in either horizontal or vertical orientation depending on the variant chosen.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e28-element log-periodic UHF design covering 470–694 MHz (channels 21–48)\u003c\/li\u003e\n\u003cli\u003e12.5 dB gain with 27 dB front-to-back ratio\u003c\/li\u003e\n\u003cli\u003eMechanical redesign for enhanced gain and 4G\/5G noise rejection\u003c\/li\u003e\n\u003cli\u003eHorizontal polarisation; H\/V version also available\u003c\/li\u003e\n\u003cli\u003eMast diameter compatibility: 20–50 mm\u003c\/li\u003e\n\u003cli\u003eAntenna length: 118 cm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Benefits\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThe 27 dB front-to-back ratio suppresses interference from behind the antenna, improving signal clarity in crowded reception environments\u003c\/li\u003e\n\u003cli\u003eBuilt-in 4G\/5G noise protection reduces interference from mobile network towers without requiring a separate filter\u003c\/li\u003e\n\u003cli\u003eHigh-quality materials provide durable mechanical resistance for long outdoor service life\u003c\/li\u003e\n\u003cli\u003eCompact packaging dimensions reduce transport and storage costs for installers\u003c\/li\u003e\n\u003cli\u003eFour model variants (with\/without F-connector, H or H\/V polarisation) let installers choose the exact configuration needed\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Log-periodic UHF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency Range:\u003c\/strong\u003e 470–694 MHz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChannels:\u003c\/strong\u003e 21–48\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Elements:\u003c\/strong\u003e 28\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImpedance:\u003c\/strong\u003e 75 Ohm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGain:\u003c\/strong\u003e 12.5 dB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFront\/Back Ratio:\u003c\/strong\u003e 27 dB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePolarisation:\u003c\/strong\u003e Horizontal (this variant)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBeam Width (Horizontal):\u003c\/strong\u003e 30°–39°\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBeam Width (Vertical):\u003c\/strong\u003e 42°–51°\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAntenna Length:\u003c\/strong\u003e 118 cm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupported Mast Diameter:\u003c\/strong\u003e 20–50 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector:\u003c\/strong\u003e None (this variant)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eWhy You'll Love It\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThe absence of a connector on this variant keeps installation flexible — attach the cable connection method of your choice\u003c\/li\u003e\n\u003cli\u003eThe 118 cm antenna length fits standard mast installations without special extensions\u003c\/li\u003e\n\u003cli\u003eChoosing the F-connector variant (P2845-7 F) allows tool-free coaxial connection on the same antenna body\u003c\/li\u003e\n\u003cli\u003eThe H\/V version (P2845-7 H\/V) supports vertical polarisation for vertical-broadcast areas without buying a separate unit\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Iskra","offers":[{"title":"Default Title","offer_id":56579844211070,"sku":"202158","price":18.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0961\/2250\/3550\/files\/15675323875710.webp?v=1779641023","url":"https:\/\/lynk.gr\/en-us\/products\/iskra-p2845-7-log-antenna-uhf-gain-12-5-db","provider":"Lynk.gr","version":"1.0","type":"link"}
