LDF 5 ac 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 a dish of up to 100 cm in diameter, it is possible to obtain antenna amplification of up to 33 dBi. The device comes preinstalled with RouterOS and is ready to use. LDF 5 ac is equipped with a Gigabit port and supports 802.11ac for higher throughput. - LDF 5 ac-US (USA) is factory locked for 5170-5250MHz and 5725-5835MHz frequencies. This lock can not be removed. - LDF 5 ac (International) supports 5150MHz-5875MHz range (Specific frequency range can be limited by country regulations).
