{"product_id":"west-penn-812bk1000","title":"West Penn 812BK1000 RG-58A\/U 50 Ohm Coaxial Bulk Cable","description":"\u003cp\u003eThe West Penn 812BK1000 is a 1000-foot spool of RG-58A\/U type 50-ohm coaxial cable designed for RF transmission, broadcast signal distribution, and wireless communication infrastructure. It targets systems integrators, broadcast engineers, and installation teams who need a reliable, bulk-quantity coax for permanent runs where consistent impedance and low capacitance are non-negotiable.\u003c\/p\u003e\u003cp\u003eThe dual-layer shield — 100% bi-foil aluminum paired with a 95% tinned copper braid — delivers robust rejection of RF interference, making this cable well-suited for antenna feeds, distributed antenna systems, and video transmission backbones in installed environments. The gas-injected polyethylene insulation supports a 78% nominal velocity of propagation, which is critical when calculating electrical length in time-sensitive broadcast and RF applications.\u003c\/p\u003e\u003cp\u003eRated NEC Type CM, this cable meets code requirements for general-purpose in-wall and plenum-adjacent installations. The tinned copper conductor resists oxidation for long-term connection integrity at termination points, and the 1000-foot spool format reduces splicing and simplifies large-scale facility wiring projects. The CN-BM53-13 connector is the manufacturer-recommended termination for this cable.\u003c\/p\u003e","brand":"West Penn Wire (Belden, Inc.)","offers":[{"title":"Default Title","offer_id":52451942957240,"sku":"202276","price":365.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0871\/7382\/4696\/files\/202276_WESTPEN-812BK1000_ALT01sqr.jpg?v=1783609003","url":"https:\/\/soundpro.com\/products\/west-penn-812bk1000","provider":"SoundPro","version":"1.0","type":"link"}
