A distributed satellite antenna system (DAS) is a system of spatially separate, geographically separated satellite antenna nodes linked to an information source through a transport medium such as a vehicle or boat that offers wireless connectivity within a building or area. A DAS system generally consists of two main elements – the satellite dish antenna and the transmission link, which may be a wired or wireless connection. DAS antenna systems are usually at least 2 miles from the source of the signal, and satellite dish antenna arrays typically are at least 8 miles from the satellite. Some DAS systems are designed to offer coverage beyond a specific coverage area, but they are limited to satellite dishes that are within a certain range of each other. A DAS system can provide the required connectivity within a limited area, and the satellite itself can offer location accuracy if it’s installed in a building with an unobstructed view.

Satellite dishes are mounted to buildings in several different ways – on poles, on rooflines, on structures such as buildings, garages, and barns, on poles, and on roofs, on the ground, or on structures such as houses. Most satellite dishes mount vertically on buildings, although some allow a roof-mounted mounting option. A DAS satellite system can provide wireless connectivity to an area using satellite dishes mounted on buildings. DAS satellite systems are commonly used to provide mobility, including to a hospital or doctor’s office where satellite coverage is not available, to a military base or airport where satellite reception is necessary, and to homes and businesses where wireless connections are necessary, such as to deliver internet. Many other applications for DAS systems exist and DAS technology continues to develop.
A DAS satellite dish antenna collects the signals from a satellite that is orbiting above it and then passes them on to an antenna mounted on the vehicle. The vehicle transmits the signal to the vehicle antenna, which passes on the signal to the transmitter on the satellite dish. The transmitter then transmits the data to the satellite, which then passes on the signal to the antenna on the ground. The antenna on the satellite detects the transmitted signal and receives it and turns it into a signal back to the receiver on the satellite dish antenna on the satellite. Once the signal reaches the receiver, the antenna transmits the signal back to the satellite again receives the data. until the signal is complete, the receiver transmits it back to the receiver, allowing the satellite to function like a wireless hot spot.
