What is a dome system?
The technical components of the satellite system are hidden under a plastic dome. The compact antenna is usually permanently installed on the roof of the caravan or motorhome and protrudes slightly above the normal installation height. For a detailed description, see dome or flat antenna.
What is a coaxial cable?
Coaxial cables are two-core cables. Since coaxial cables are particularly suitable for transmitting high-frequency broadband signals, they are often used for the transmission of broadcast signals.
Internet via satellite
A satellite dish receives the data and transmits it to a modem. All web-enabled devices can log into the network and go online. Internet via satellite does not require any cables and is available everywhere. Depending on your provider and contract, special VoIP services can also be booked.
What is a parabolic dish? (colloquial)
A parabolic dish is basically an antenna. The curved shape of the parabolic antenna is reminiscent of a dish – hence the name. The task of the antenna/dish is to receive signals from distant television satellites. These signals travel about 36,000 km before reaching their destination. Because of that, they are very weak and have to be received in the parabolic dish. There, they are bundled in the focal point so that they can be used. It is important that you align the satellite dish with the satellite as precisely as possible. The signal is particularly strong at the so-called focal point of the satellite dish and is received and processed from there via an LNB. Via a coaxial cable, it is then forwarded to a receiver or a distributor such as a satellite system.
What does TWIN LNB mean?
LNB stands for low-noise block downconverter, meaning it’s a low-noise signal converter or signal amplifier. The LNB is a component of a microwave receiver and is located at the focal point of the parabolic dish. There, the LNB amplifies the weak signals/microwaves received from satellites in space and translates them into a low-noise and low-loss intermediate frequency. This translation is necessary so that the data can be transported to a satellite receiver via a coaxial cable.
TWIN LNB means that up to two receivers can access the satellite signal independently of each other. In short, that means that with the right equipment, you no longer have to argue about what to watch on holiday.
What is a receiver?
A receiver is responsible for receiving and decoding or processing signals. Generally, this includes audio, video and text data that the receiver can process for various output devices. That means that without a receiver, there is no picture, sound or text on the screen or on the radio.
What are dome or flat antennas?
These antennas have a few things in common. Both have a very compact design, no protruding arm and a fully integrated LNB. With both antennas, the name says it all: dome antennas and flat antennas hide their technical components behind a dome or a square flat housing, respectively. That way, the components are shielded from the outside, which ultimately makes cleaning and maintenance easier. In addition, both antenna types can be permanently installed on a recreational vehicle. However, flat antennas were specially developed for installation on motorhomes. Both antenna shapes are aerodynamic. If you have a dome antenna, always keep in mind that it makes your vehicle higher before driving under low bridges, for example. But despite all the advantages this type of antenna offers, the reception performance of a parabolic antenna is still significantly better. If you want to camp in very remote areas, go for the parabolic dish.
