The cable is 20 inches long. It can be used with Nebra Outdoor and Milesight Helium miners if connecting to an N-male antenna, and has applications in WiFi and Meshtastic as well.\u003cbr\u003e\u003cbr\u003eWe recommend this extension cable compared to some others online because this is a special 400-grade low-loss cable. The antenna to which you will connect this to has a gain. Let's say you will be connecting this to an 8 dBi gain antenna. As the cable in between the antenna and device gets longer, you will experience gain loss. With lesser-grade shielded extension cables, the huge drop in gain will mean much worse performance. Our special low loss cable limits the cable loss factor and preserves the high gain of your antenna.\u003cbr\u003e\u003cbr\u003eMade in the USA.

How do I know if this is the right extension cable for me?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eCheck with the maker or seller of your antenna to find out what type of connector it has. As a rule of thumb, you want to get an RP-SMA male to RP-SMA female extension cable when the antenna you have can connect directly to the RP-SMA connector on your wireless adapter if you wanted it to. That would mean your antenna also has an RP-SMA connector, and this would be the right cable for you. If your antenna has another type of connector, meaning it is not possible for you to connect it directly to the RP-SMA connector on your wireless adapter, then please contact us so we can help you locate the right cable for your needs. Additionally, we always recommend getting as close to the length you need as possible. If you are only trying to go 10 feet, don't buy a 30-foot cable as you will have more gain loss than you need.\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003eWarranty \u0026amp; Support:\u003cbr data-mce-fragment=\"1\"\u003e\u003c\/strong\u003eComplimentary\u003cspan style=\"color: #000000;\"\u003e \u003c\/span\u003e\u003ca href=\"https:\/\/store.rokland.com\/pages\/rokland-technologies-support\" data-mce-fragment=\"1\"\u003eTelephone and Email\/Live Chat Support (Click Here)\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003eState sales tax of 7.5% will be added to FLORIDA purchases only.
