Coaxial cable is a type of shielded, electrical conducting cable used to transmit analog and digital signals. The initials RG stand for Radio Guide and are used to describe different types of coaxial cable. RG-178 cables are most commonly used for transmitting high-frequency signals. As such, they are often employed for the purpose of cabling between Wi-Fi routers and antennas. The SMA male and SMA female connectors that terminate this cable are also widely compatible with many wireless network implements. SMA stands for SubMiniature version A and is a form of RF coaxial connector with 50 ohms impedance and a performance frequency of up to 18GHz. SMA connectors feature a screw-type coupling mechanism and are frequently employed in bulkheads and patch panels because of the their diminutive size. For a widely compatible, resilient addition to your data infrastructure, look no further than this RG-178 coaxial cable with SMA male to SMA female connectors.\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cspan color:=\"\" font-size:=\"\" new=\"\" style=\"font-family: \" times=\"\"\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n\t\u003cli\u003e\u003cspan color:=\"\" font-size:=\"\" new=\"\" style=\"font-family: \" times=\"\"\u003eRG-178 Coaxial Cable with SMA Male to SMA Male Connectors\u003c\/span\u003e\u003c\/li\u003e\n\t\u003cli\u003e\u003cspan color:=\"\" font-size:=\"\" new=\"\" style=\"font-family: \" times=\"\"\u003eSMA stands for SubMiniature version A, a type of RF coaxial connector with 50 ohms impedance and a frequency range of up to 18GHz\u003c\/span\u003e\u003c\/li\u003e\n\t\u003cli\u003e\u003cspan color:=\"\" font-size:=\"\" new=\"\" style=\"font-family: \" times=\"\"\u003e30cm   ;\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003cdiv\u003e \u003c\/div\u003e\n\n\u003cdiv\u003e \u003c\/div\u003e\n\u003c\/div\u003e\n\n\u003cdiv style=\"font-family: Arial, Helvetica, sans-serif;\"\u003e\n\u003cdiv\u003e \u003c\/div\u003e\n\u003c\/div\u003e","brand":"Eletechsup Original Factory Official‌ Store ","offers":[{"title":"Default Title","offer_id":46537021489309,"sku":"TB151","price":6.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0707\/8622\/0189\/files\/10_61be64d5-9c29-4c45-a486-1651f1b9a989.jpg?v=1740746806"},{"product_id":"rt5bf01-433m-wireless-controller-rs485-io-point-to-point-master-slave-rf-transceiver","title":"RT5BF01 433M Wireless Controller RS485 IO Point-to-Point Master-Slave RF Transceiver","description":"\u003cdiv id=\"ds_div\"\u003e\n\u003cdiv open=\"\" style=\"box-sizing: content-box;
