The OneLinkMore WiFi Antenna is a versatile dual-band antenna supporting 2.4GHz and 5.8GHz frequencies. It features an RP-SMA male connector, making it compatible with a wide range of wireless routers and desktop PC WiFi cards. With a gain of 5dBi, it offers a modest improvement in signal reception for areas with weak coverage. This package includes two white antennas, each measuring approximately 195 mm in length. The compact design fits easily on a desk or in a network rack. Beyond routers, it can also be used with FPV drones, WiFi adapters, and any device equipped with an RP-SMA interface. The connector type is RP-SMA male. Compatible devices include popular routers such as ASUS RT-AC88U, RT-AC68U, NETGEAR EX6200, TP-Link AC15, AC3200, and AC66U. It also works with desktop Mini PCI-E WiFi cards and USB WiFi adapters that support external antennas. Frequency range: 2.4GHz (2400-2500MHz) and 5.8GHz (4900-5900MHz) Impedance: 50Ω VSWR: ≤1.5 Polarization: Vertical * Maximum input power: 50W Please verify your device's connector type before purchase. Some older or specialized equipment may use RP-SMA female or standard SMA connectors, which are not compatible. The OneLinkMore WiFi Antenna is an entry-to-mid-range universal antenna sold as a 2-pack. It is priced affordably, making it a cost-effective choice for replacing stock router antennas or adding external antennas to a desktop WiFi card. Check the retailer's page for the latest price. It does not match the performance of high-gain or directional antennas, but offers excellent value for the price. Users with weak signal in certain rooms: Replacing your router's stock antennas with these 5dBi units can extend coverage. However, if walls or obstacles are severe, consider a mesh system or repeater instead. Desktop PC users adding external antennas to a WiFi card: Many Mini PCI-E cards use RP-SMA connectors. Mounting the antenna outside the case can significantly improve reception compared to internal antennas. Hobbyists using FPV drones or wireless HDMI extenders with RP-SMA ports: The universal connector allows reuse across multiple devices. Be mindful of weight and size for drone applications. Budget-conscious users needing a quick antenna upgrade: The 2-pack price is very competitive. If you need higher gain or specialized frequency support, look for purpose-built antennas. Always confirm your device's connector type. RP-SMA male is common but not universal. 5dBi gain is modest; do not expect dramatic improvements in heavily obstructed environments. This antenna is designed for indoor use only. It is not weatherproof. Replacing router antennas may affect regulatory compliance (e. g. , Japanese Technical Standards). Use at your own risk or choose a certified product. * The antenna supports 2.4GHz and 5.8GHz, but not the 5GHz band (5.15-5.35GHz). Check your router's supported frequencies. Q: Can I use this antenna with an ASUS RT-AC68U? A: Yes, the RT-AC68U uses RP-SMA male connectors, so these antennas can be attached directly. Both 2.4GHz and 5GHz bands will work after replacement. Q: Do I need any additional parts to use this with a desktop WiFi card? A: Most Mini PCI-E WiFi cards (e. g. , Intel AX200) have RP-SMA compatible antenna ports. If your card uses IPEX connectors, you will need an IPEX-to-RP-SMA adapter cable. Q: Can I use only one antenna from the 2-pack? A: Yes, a single antenna will work. However, using both enables diversity reception, which improves connection stability. The spare can be kept as a backup. ### Product Disclosure (Amazon) - Manufacturer: onelinkmore - Brand: OneLinkMore - Seller: Chappy7 - Fulfilled by: Chappy7 - ASIN: B0BN3R578D - Note: This article covers a manufacturer-made product based on Amazon listing details.
