{"product_id":"arnoflex-cable-coaxial-rg58-pur-vhf-50-ohm","title":"RG58 PUR coaxial cable for VHF","description":"\u003cp\u003e\n    Designed for demanding marine environments, the Arnoflex 58 PUR coaxial cable provides a reliable solution for VHF communication systems and other high-frequency applications up to 1 GHz. This 50 Ohm cable stands out for its optimized structure for durability and performance.\n\u003c\/p\u003e\n\u003ch3\u003eDesign and materials\u003c\/h3\u003e\n\u003cp\u003e\n    The Arnoflex 58 PUR cable features a tinned copper core made of 19 strands of 0.18 mm, ensuring good conductivity and corrosion resistance. The dielectric is made of low-density polyethylene with a diameter of 2.95 mm (± 0.10 mm), providing low signal loss. The shielding braid is made of tinned copper with 94% coverage (144 strands of 0.10 mm), contributing to excellent shielding effectiveness (\u003e 57 dB between 100 and 900 MHz). The outer jacket is made of polyurethane (PUR) in black, with a diameter of 5.00 mm (± 0.20 mm), giving the cable superior resistance to UV, abrasion, hydrocarbons, and temperature variations. This cable complies with the UL MIL C 17 standard, attesting to its robustness for critical applications.\n\u003c\/p\u003e\n\u003ch3\u003eElectrical and mechanical performance\u003c\/h3\u003e\n\u003cp\u003e\n    Electrically, this cable has a nominal impedance of 50 Ohm ± 3 and a capacitance of 100 pF\/m. The propagation velocity is 66%. The core resistance is 36.5 Ohm\/km and the braid resistance is 15.0 Ohm\/km. It can withstand a voltage of 4.0 kV during the spark test on the jacket. Typical attenuation values are 11.0 dB\/100m at 50 MHz, 15.3 dB\/100m at 100 MHz, and 58.3 dB\/100m at 1000 MHz, with corresponding power ratings of 268 W at 50 MHz and 60 W at 1000 MHz. Mechanically, the cable weighs 35.6 kg\/km and offers an operating temperature range of -50 to +90 °C, with a minimum bending radius of 5 times the outer diameter for a single bend and 10 times for repeated bending.\n\u003c\/p\u003e\n\u003ch3\u003ePositioning and uses\u003c\/h3\u003e\n\u003cp\u003e\n    The Arnoflex 58 PUR is positioned as an alternative to standard RG58 PVC cables, offering enhanced durability for outdoor installations thanks to its PUR jacket. Unlike LSZH (Low Smoke Zero Halogen) cables, which are primarily designed for indoor fire safety, PUR is specifically suited to external environmental constraints. For applications requiring 75 Ohm impedance, other references such as RG59 should be considered. This cable is compatible with a wide range of connectors (BNC, TNC, N, SMA, Fakra, etc.), allowing integration into various marine and industrial radiofrequency systems.\n\u003c\/p\u003e","brand":"Skysat","offers":[{"title":"Default Title","offer_id":53723796570452,"sku":"050168","price":4.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0988\/3274\/4788\/files\/odoo-050168-main.jpg?v=1779298496","url":"https:\/\/skysat.fr\/en-us\/products\/arnoflex-rg58-pur-coaxial-cable-vhf-50-ohm-7","provider":"Skysat","version":"1.0","type":"link"}
