Mast amplifiers
If the reception is not satisfactory at an individual TV antenna installation, it is necessary to install a mast antenna amplifier.
A mast antenna amplifier can have 1, 2, 3, or 4 inputs for VHF and UHF.
The cable which connects the antenna to the mast amplifier can be flat 300Ù or coaxial 75Ù.
A coaxial cable 75Ù will be necessary connected to the output of the mast amplifier.
This coaxial cable will reach the TV and be connected with the power supply to the contact (Antenna).
Another length of coaxial cable 75Ù will be connected from the power supply contact (TV) to the input of the TV set.
