(8m) Antenna extension coaxial cable RP-SMA Male to N-Male 400 grade low loss","description":"\u003cp\u003e\u003cspan style=\"color: #000000;\"\u003eThis special low-loss RP-SMA male to N-Male extension cable from ALFA Networks is RFC-400 equivalent shielded. The cable is 8m long (~26 feet) and can be used to put an extension between an RP-SMA antenna connector on a Meshtastic device with RP-SMA. a Wi-Fi USB adapter or PCI card and an antenna with an N-female connector. \u003cbr\u003e\u003cbr\u003eWe recommend this extension cable compared to some others online because this is ALFA Networks branded and is also a special low-loss cable (RFC-400 NL Low Loss 50 OHM). What does this mean? Let's say for example you will be connecting this to a 12 dBi gain antenna. As the cable in between the antenna and adapter gets longer, you will experience cable loss, which is a drop in the signal gain of the antenna. With low-quality unshielded extension cables, the huge drop in gain will mean a much lesser range. Our special low loss cable limits the cable loss factor and preserves the high gain of your antenna.\u003c\/span\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-mce-fragment=\"1\"\u003e\u003cspan style=\"color: #000000;\"\u003eWe do recommend\u003c\/span\u003e \u003ca href=\"https:\/\/store.rokland.com\/products\/tape-helium-antenna-and-coaxial-cable-self-fusing-silicone-heat-water-resistant\" data-mce-fragment=\"1\"\u003eRokTape\u003c\/a\u003e \u003cspan style=\"color: #000000;\"\u003eto seal all outdoor connection points. \u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: #000000;\"\u003e\u003cb\u003eCompare gain loss of this cable:\u003cbr\u003e\u003c\/b\u003e915 MHz application: -0.95 dB (Helium mining\/LoRa device)\u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"color: #000000;\"\u003eWiFi 2.4 GHz application: -1.65 dB (standard home WiFi networking)\u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"color: #000000;\"\u003eWiFi 5 GHz application: -2.51 dB (dual-band 2.4\/5 GHz WiFi to 5 GHz networks)\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan style=\"color: #000000;\"\u003eCompare this to a cheaper RG-58 shielded cable of the same length- the gain-loss would be -3.9 dB for 915 MHz, -7.5 dB for 2.4 GHz WiFi, and a whopping -12.9 dB for 5 GHz WiFi\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan style=\"color: #000000;\"\u003e\u003cstrong\u003eThat means standard RG-58 cables have about 4x times as much gain loss as this cable!\u003c\/strong\u003e\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan style=\"color: #000000;\"\u003eIf you invested a lot in your antenna, it is worth the extra amount to get a 400-grade low-loss cable to maximize your antenna performance.

In other words, all antenna cables are not basically the same. When you use a cable in between the antenna and the WiFi adapter, the gain of the antenna decreases markedly. This is a factor known as cable loss. The $3 and $4 RP-SMA extension cables in abundance on eBay have no low loss shielding. Using them will cause significant gain loss- so much so you may find your factory antenna connected directly to your adapter will begin to work better than your expensive high gain outdoor antenna. To limit gain loss, you need a thick shielded low loss cable, from a trusted manufacturer like ALFA Networks. It has special low loss shielding to limit your gain loss and simply works much better than cheap cables that have no low loss shielding.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"color: #ff0000;\"\u003e\u003cb\u003e2.

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.\u003c\/span\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: #000000;\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003eWarranty \u0026amp; Support:\u003cbr data-mce-fragment=\"1\"\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003cspan data-mce-fragment=\"1\"\u003e\u003cspan style=\"color: #000000;\"\u003eComplimentary\u003c\/span\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\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: #000000;\"\u003e\u003cstrong\u003eSales tax is required in many states and will be added at checkout if applicable to your delivery state.
