The GRC SandFly 75cm antenna is designed to transmit and receive in Ka-band, providing an extremely light-weight segmented reflector.

Made from carbon fibre and weighing less than 20Kgs the SandFly can be carried by an individual in a handheld transit case and due its four piece design, can be distributed amongst a team for even easier transportation.

As no tools are required for its construction the SandFly can be simply deployed by a single person and positioned on the ground, in a vehicle or as permanently mounted reflector. The SandFly also features interchangeable modems and transceivers, making it ideal for ‘go capture’ or news spotter applications.

The SandFly is fully endorsed by Avanti for use on its fleet of Ka-band satellites and this market leading combination provides a cost effective mobile satellite solution for all users requiring a flexible, mobile Ka-band service. Avanti is a leading global satellite operator, with vast experience of deploying high speed data communications to consumers, enterprises, governments and carrier services beyond the reach of fibre.
