How to choose and buy a well-known brand antenna for receiving terrestrial television and radio signals in the sea
How to choose an omnidirectional TV antenna on a ship
The high-quality reception of terrestrial analog and digital signals in the open sea in order to provide ship communications, television and other types of communications with the outside world makes the highest demands on the appropriate receiving equipment, in particular marine omnidirectional antennas. The task of equipping movable objects with television equipment is of great importance in connection with Continue reading

The acronym LNB stands for Low Noise Block. This device is installed in front of a satellite dish, which receives a very low signal and amplifies it, changes the signal to lower frequencies and transmits them via cable to the receiver.
The expression Low Noise refers to the quality of the first transistor preamp. Quality varies in units designated as “noise temperature” or “noise figure”. The lower the noise temperature, the better. So, LNB with a noise temperature of 100 K is twice as good as – 200K. C-band LNBs typically have the lowest noise temperature, and Ka-band LNBs have the Continue reading
