What does the installation involve?
The majority of receivers can be attached to the house, somewhere near the roof to give optimum line of sight. It is a discreet rectangular box which is much smaller than a satellite dish. Wiring then needs to come down and a hole will be drilled to allow it into the house. It is hen connected to a domestic power supply. Another wire connects from this to a router which can then transmit the signal around a house, or connect directly to a computer.
It is a low voltage installation.
