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
Satellite antennas are made as solid / all-stamped, mesh and precast / sectional. The solid ones are made of a whole metal sheet and have a shape without technical holes and joints. Their signal reception quality is better than the others, and the design is less prone to kinks and defects during operation.
Mesh antennas are assembled from strips, forming a receiving grid. Their advantage is less windage, so mesh satellite dishes are preferred in areas with increased wind load.
Prefabricated antennas are made of petals and can be compactly packed for transportation and long-term storage. They, like sectional ones, are convenient for regular transfer, as they are easy to fold and allow you to quickly deploy the system. Cons of the design – in the weak joints of the petals, which are easily broken and require regular professional maintenance.
Mesh satellite dishes have slightly worse signal quality than all-metal antennas, but not due to technical holes. Since for the correct reflection of the beam the shape of the mirror must be strictly parabolic, it is Continue reading
