It supports dual-band 2.4GHz and 5.8GHz frequencies with a gain of 8 dBi, offering a significant improvement over many stock antennas. The package includes two RP-SMA male antennas and two U. FL (MHF4) to RP-SMA female extension cables, each 20 cm long, allowing you to place the antennas outside your PC case for better signal reception. Each antenna measures about 160 mm in length, and the impedance is 50 ohms. The maximum range is rated at 15 meters. This kit is a practical choice for upgrading the Wi-Fi performance of a desktop or laptop that uses an M.2 NGFF card with U. FL connectors. This antenna kit is specifically designed for M.2 NGFF (Key E or Key A+E) Wi-Fi cards. The card must have U. FL (MHF4) antenna connectors. Some cards use IPEX4 or IPEX1 connectors, which are not compatible without adapters. The extension cables convert from U. FL (female) to RP-SMA (female), and the antennas have RP-SMA (male) connectors. The antennas are omnidirectional rod types. They do not have magnetic bases or stands, so you will need to place them on a desk or mount them using third-party accessories. Important: This kit is not compatible with mini PCIe Wi-Fi cards. If your laptop or desktop uses a mini PCIe card, you will need a different adapter. Tenmory is a brand known for affordable PC accessories. This antenna kit is widely available on and other online retailers. It sits in the entry-level segment, providing a cost-effective way to improve Wi-Fi signal strength. Check the retailer's page for the latest price. The warranty is the standard 30-day return policy from the seller. The package includes two antennas, two extension cables, and a simple instruction sheet. Users with desktop PCs that have an M.2 Wi-Fi card but poor signal due to the internal antenna being inside a metal case: This kit allows you to move the antenna outside for a clear line of sight to the router. The 8 dBi gain helps in weak signal areas. However, you need to have a cutout or slot in the case to route the cables. Repairing a laptop with a broken internal antenna: If your laptop's Wi-Fi antenna is damaged and the card uses U. FL connectors, this kit can replace it. Be aware that the 20 cm cables may be short for some laptop chassis, and you will need to disassemble the laptop to access the card. Enthusiasts building a custom PC with a Wi-Fi card: If your motherboard has an M.2 slot for Wi-Fi, you can add a card like Intel AX210 and use this antenna kit for a clean external antenna solution. Not recommended for: Users who need a magnetic mount or a desktop stand, or those with mini PCIe cards. Also, if your Wi-Fi card uses a different connector (e. g. , IPEX4), you will need an adapter or a different kit. ### Product Disclosure (Amazon) - Manufacturer: Tenmory - Seller: Amazon US - Fulfilled by: Amazon US - ASIN: B07QKF18KM - Note: This article covers a manufacturer-made product based on Amazon listing details.
