• 🔹 RIGHT ANGLE (90°) DESIGN – PERFECT FOR TIGHT SPACES & ITX BUILDS – Unlike standard straight antennas that stick out awkwardly, this 90° right angle design allows the antenna to fold flush against your device, making it ideal for small form factor (SFF) PCs, ITX builds, and space-constrained setups . The articulating hinge lets you position the antenna vertically, at a right angle, or anywhere in between – giving you the flexibility to route it around obstructions and achieve optimal signal reception . Whether you’re building in a tiny ITX case or need to tuck antennas behind a monitor, this compact right-angle design keeps your setup clean and professional.
• 🔹 TRUE TRI-BAND COVERAGE – 2.4GHz / 5GHz / 5.8GHz – Supports 2.4GHz (2400-2500MHz) for long-range wall penetration, 5GHz (5150-5850MHz) for high-speed gaming and streaming, and 5.8GHz for FPV drones and wireless video transmission . Fully compatible with WiFi 6, WiFi 5, Bluetooth, and legacy 802.11 a/b/g/n/ac standards. The 3dBi gain provides balanced, spherical coverage – perfect for desktop environments where your router is on the same floor .
• 🔹 RP-SMA MALE CONNECTOR – UNIVERSAL COMPATIBILITY – Features standard RP-SMA Male (center hole – no pin) connectors, compatible with thousands of devices that have RP-SMA Female ports . Works with: PC & Motherboards: ASUS, MSI, Gigabyte gaming motherboards with WiFi; ITX builds; M.2 WiFi cards Network Cards: PCIe WiFi 6/6E cards (Intel AX200/AX210, Killer, etc.), USB WiFi adapters Routers & Access Points: ASUS, TP-Link, Netgear with RP-SMA ports Other Devices: IP security cameras, FPV drone video transmitters, Bluetooth receivers, wireless bridges
• 🔹 2x2 MIMO READY – IMPROVED THROUGHPUT – The dual‑antenna configuration supports 2x2 MIMO technology for simultaneous data transmission and reception – delivering faster speeds, lower latency, and more stable connections. For best MIMO performance, position antennas at least a quarter‑wavelength apart and keep them away from large metal objects.
• 🔹 PERFECT FOR SFF BUILDS & MINI PCs – Ideal for: ITX / Small Form Factor PCs – Fits crowded rear I/O panels where standard antennas won‘t fit. Users have successfully replaced missing antennas on Dell OptiPlex mini PCs with this compact right‑angle design. Desktop PC / PCIe WiFi Cards – Clean, low‑profile alternative to bulky OEM antennas SFF Routers & Access Points – Compact upgrade for space‑constrained networking FPV Drones & Video Transmitters – 5.8GHz band provides clear video feed IP Security & Wireless Backup Cameras – Reliable signal for monitoring Bluetooth Receivers & Audio Devices – Improved range for wireless peripherals
• 🔹 DURABLE CONSTRUCTION – COMPACT & RELIABLE – Lightweight design at approximately 1.57 inches (4cm) long, weighing only ~10g per antenna. Gold‑plated connectors resist oxidation and ensure optimal signal transfer. Operating temperature: -20°C to +80°C. Solid construction with precision‑molded threads and soldered feedlines minimize return loss.
• 💡 Perfect Replacement for Lost or Damaged Antennas – If you’ve lost the WiFi antenna on your Dell Optiplex mini PC, gaming motherboard, or ITX build, these antennas are the ideal replacement . Users report they “fit perfectly and you can rotate it anyway you like so it’s not sticking straight back” .
