Built for VHF, UHF, and FM coverage across channels 2–60, it supports common rooftop and attic antenna setups where added amplification can improve usable signal levels before the coax run to your television or tuner.\u003c\/p\u003e \u003cp\u003eFor cleaner reception in today’s crowded RF environments, the SB51 includes an LTE filter to reduce potential interference from nearby cellular signals, along with a switchable FM trap to help manage strong FM broadcasts. With variable gain from 20 to 30 dB, you can dial in amplification to match your installation needs and avoid excessive gain in strong-signal areas.\u003c\/p\u003e \u003ch3\u003eKey Features of the SB51 Adjustable-Gain Antenna Preamp\u003c\/h3\u003e \u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eAdjustable Gain Control:\u003c\/strong\u003e Variable gain from 20–30 dB to fine-tune amplification for your antenna and signal conditions.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eWideband Reception Support:\u003c\/strong\u003e Designed for VHF\/UHF\/FM coverage across channels 2–60.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eLTE Filter:\u003c\/strong\u003e Helps reduce interference from nearby LTE\/cellular signals for more stable reception.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eSwitchable FM Trap:\u003c\/strong\u003e Optional FM filtering to help mitigate overload from strong local FM stations.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eSingle-Input Design:\u003c\/strong\u003e Simple, streamlined connection for single-antenna installations.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eMast-Mount Installation:\u003c\/strong\u003e Preamp mounts at the antenna location to amplify signal early in the signal path.\u003c\/li\u003e \u003c\/ul\u003e \u003ch3\u003eTechnical Specifications\u003c\/h3\u003e \u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e SB51\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Preamp (VHF\/UHF\/FM)\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eSupported Channels:\u003c\/strong\u003e 2–60\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eGain:\u003c\/strong\u003e Adjustable 20–30 dB\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eInput:\u003c\/strong\u003e Single input\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eFiltering:\u003c\/strong\u003e LTE filter; switchable FM trap\u003c\/li\u003e \u003c\/ul\u003e \u003ch3\u003eWhat’s Included\u003c\/h3\u003e \u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eMast Mounted Preamp:\u003c\/strong\u003e Outdoor preamplifier unit for installation near the antenna.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eIndoor Power Supply:\u003c\/strong\u003e Provides power for the preamp from inside the home.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003ePower Inserter:\u003c\/strong\u003e Sends power up the coax line to the mast-mounted preamp.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Sky Blue","offers":[{"title":"Default Title","offer_id":45860435001541,"sku":"SKYB-SB51","price":149.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0630\/3085\/3829\/files\/79ee946563b80013f204f4fc05bd422f.jpg?v=1771542526","url":"https:\/\/avlgear.com\/products\/sky-blue-sb51-single-input-mast-mount-tv-preamp-vhf-uhf-fm-20-30-db-gain","provider":"AVLGEAR","version":"1.0","type":"link"}
