MikroTik ACOMNIRPSMA 5dBi 2.4GHz Omnidirectional WiFi Antenna RP-SMA

The Mikrotik ACOMNIRPSMA is a 2.4 GHz outdoor dipole antenna designed for deployment in demanding environments where weather resistance is essential. Built around a PCB dipole element and terminated with an RP-SMA Male connector, it delivers 5.0 dBi of gain across the full 2400–2500 MHz band with a true 360-degree horizontal radiation pattern, making it well suited for omnidirectional coverage in outdoor campus environments such as campgrounds, trailer parks, and open common areas. Because the antenna is waterproof, it can be mounted directly to compatible MikroTik enclosures without an additional protective cover, simplifying installation and reducing hardware overhead. Two units used together on a dual-connector device enable a 2×2 MIMO configuration, extending both range and throughput capacity compared with a single-antenna setup.

Key features & benefits

• Full 2.4 GHz Band Coverage — Operates across 2400–2500 MHz, covering the entire 2.4 GHz ISM band for broad compatibility with standard Wi-Fi deployments.
• 5.0 dBi Gain with 360° Horizontal Pattern — The omnidirectional radiation pattern and 5.0 ± 0.3 dBi gain provide consistent, even coverage in all horizontal directions without the need to aim or orient the antenna toward client devices.
• Waterproof Construction — Weatherproof build allows outdoor installation without additional enclosure protection when properly connected, reducing complexity in exposed deployments.
• PCB Dipole Element — A printed circuit board dipole radiator provides a compact, durable form factor suitable for permanent outdoor infrastructure.
• RP-SMA Male Connector — Standard RP-SMA Male termination ensures straightforward connection to compatible MikroTik access points and other devices sharing this connector type.
• MIMO-Ready in Pairs — Two antennas used together on a dual-port device enable a 2×2 MIMO configuration, supporting spatial multiplexing for improved link performance in multi-client outdoor environments.
• Low VSWR — A VSWR of ≤2.0:1 across the operating band indicates efficient power transfer between the radio and the antenna, minimizing reflected energy and maximizing radiated output.
• 50 Ω Impedance — Matched to the industry-standard 50 Ω system impedance used in virtually all Wi-Fi radio platforms, ensuring compatibility without additional matching components.
