Details
The tap is used in multiswitch installations. It is used to separate the signal from the multiswitch bus. The trunk line with signal from one Quatro LNB consists of four wires. In addition, the tapping device also separates terrestrial TV signals. The tap has a DC-transition switch which, when set to the "ON" position, passes DC voltage through the "H" paths to both branches. When set in the "OFF" position, it only passes voltage to one branch.
The die-cast housing provides high screening efficiency by preventing the penetration of interfering signals to the unit.

Designing antenna systems with the use of free software from TERRA - SatNet application. The program allows to prepare the project in graphical form, to determine signal levels in all outlets and verify if they are compliant with standards, and to decide whether to use equalization function of the amplifiers. The program enables the user to archive the designs.
