This article covers Eightwood Mini PCIe WiFiカードアンテナキット 2.4GHz 5GHz デュアルバンド.

Overview

The Eightwood Mini PCIe WiFi Card Antenna Kit is a practical upgrade for desktop PC users looking to improve their wireless reception. This kit includes two dual-band antennas (2.4GHz and 5GHz), MHF4 (IPEX) to RP-SMA pigtail cables, and PCI slot brackets for clean installation. Measuring just 47mm in height when folded at 90 degrees, these compact antennas take up minimal space on your desk or PC case. The RP-SMA male connectors ensure broad compatibility with Mini PCIe wireless cards, select motherboards, routers, and other devices. It's a cost-effective solution for boosting signal strength without cluttering your workspace.

Connectivity & Compatibility

Connector type: Antenna side — RP-SMA male (no center pin); Cable side — MHF4 (IPEX) to RP-SMA female Compatible devices: PCI/PCIe wireless network cards, Mini PCIe cards (e.g., Intel Wireless-AC 7260), desktop PC motherboards, external Wi-Fi USB adapters, wireless routers, WLAN access points, range extenders, Bluetooth modules * Important note: This kit is NOT compatible with M.2 NGFF (Key E) cards. Verify your card's interface before purchase.

Product Info

Release period: Available since 2023 (as listed on) Price range: Approximately ¥3,900 ( reference price) Warranty: Check the seller's page for manufacturer warranty details Package contents: 2× dual-band antennas (2.4/5GHz), 2× MHF4 IPEX to RP-SMA coaxial cables (20cm/8 inches), 2× PC back-slot cover brackets * Market position: Entry to mid-range. This kit offers excellent value for users seeking a simple antenna upgrade over stock options, though it lacks high-gain performance for extreme distances.

Best Use Cases

Desktop PC users wanting better Wi-Fi reception: The external antennas can capture signals that internal case antennas miss. However, with a gain of only 2.15dBi, it may not solve very long-range or heavily obstructed connections — consider a higher-gain antenna for those scenarios. DIY PC builders adding a Mini PCIe wireless card: If your card came with basic antennas, this kit provides proper bracket mounting and longer cables for a cleaner setup. Just ensure your card uses Mini PCIe, not M.2 NGFF. * Users who value a tidy workspace: The short antenna design keeps your desk uncluttered. Note that no magnetic base or adhesive is included, so you'll need the bracket or a separate stand for placement.

Things to Consider

This kit is strictly for Mini PCIe cards. M.2 NGFF (Key E) cards require a different antenna kit with the correct connector. The 2.15dBi gain is standard — don't expect dramatic range improvements in challenging environments like thick concrete walls or very distant routers. The 20cm pigtail cables are short; ensure your PC case layout allows the cables to reach the card's antenna ports. Extension cables are available separately if needed. No mounting accessories (magnets, adhesive pads) are included. Plan to use the provided slot brackets or purchase a separate antenna stand. ## FAQ
Q: Can I use this antenna kit with an Intel AX210 M.2 Wi-Fi card? A: No, this kit is designed for Mini PCIe interfaces only. M.2 NGFF (Key E) cards have a different connector and require a dedicated M.2 antenna kit. Q: Will this work as a replacement antenna for my router? A: Yes, if your router uses RP-SMA male connectors. The 2.15dBi gain is typical for stock antennas, so performance should be comparable. Q: Can I extend the cables if they're too short? A: Yes, you can use RP-SMA extension cables. Be aware that longer cable runs may introduce signal loss, so keep extensions as short as practical.
