MikroTik LDF 5 (RBLDF-5nD) 5GHz 9dBi Integrated Directional Antenna CPE, 1x 10/100 Ethernet, Passive PoE, RouterOS L3

For wireless ISPs and network integrators deploying point-to-multipoint links, the MikroTik LDF 5 (RBLDF-5nD) delivers a compact 5 GHz CPE with a 9 dBi integrated directional antenna. It connects to an access point up to several kilometers away, providing reliable broadband to a single client device via its 10/100 Mbps Ethernet port.

Key specifications

• Wireless: 802.11a/n/ac, 5 GHz band, 1x1 MIMO, up to 25 dBm output power
• Antenna: Integrated 9 dBi directional, offset satellite dish mountable
• Processor: QCA9531, 650 MHz, MIPSBE architecture
• Memory: 64 MB DDR2 RAM, 16 MB flash storage
• Interface: 1x 10/100 Mbps Ethernet with Passive PoE input (10-30 V)
• Software: RouterOS Level 3 license, supports advanced routing and firewall features
• Power consumption: up to 6 W, wide operating temperature range -40°C to 70°C

Why choose it

The LDF 5 stands out for its integrated high-gain antenna and robust outdoor design, eliminating the need for external antenna cables and reducing installation complexity. Its low power draw and passive PoE support allow for flexible deployment using standard PoE injectors or MikroTik power supplies. With RouterOS L3, you get a full-featured router with VLAN, firewall, and bandwidth management capabilities, making it suitable for both simple CPE and more advanced network edge tasks.

Ideal use cases

• Connecting a remote home or office to a wireless ISP network
• Point-to-point links for surveillance cameras or IoT gateways
• Building a low-cost wireless bridge between two locations
• Extending network coverage to outbuildings or temporary sites

Good to know

The device is designed for outdoor use and can be mounted on a standard satellite dish arm, allowing precise alignment for optimal signal. It does not include a power supply; a compatible passive PoE injector (10-30 V) is required. The single Ethernet port means it is intended for one client device or a switch for local expansion. RouterOS L3 license includes advanced features like OSPF, BGP, and MPLS, which are rarely found in this class of CPE.
