The LDF (Lite dish feed) is an outdoor wireless system with a built-in antenna, meant to be installed on satellite offset dish antennas. The dish will act as a reflector, amplifying the signal.
This means you can use any available satellite TV dish with an offset mount to quickly deploy powerful long-range wireless links. The offset mount is universal at 40 mm diameter, and the LDF can easily be placed inside it. Since the LDF itself is a tiny little package, it makes shipping and deployment simple and low cost.
Using large enough dishes, it is possible to obtain antenna amplification of 30 dB or more. All it takes is to find a spare satellite dish with an offset mount and put your LDF device. The device comes preinstalled with RouterOS and is ready to use.
