Applications
The BLAMHD11VA can be used where additional amplification is required on a Group A aerial. In a combined aerial installation, the Group A and Group B aerials can be connected to the BLACOM21AB, with the BLAMHD11VA used to amplify the Group A signal, and/or the BLAMHD11VB for Group B. The combined signal can then be fed towards the distribution equipment and TV outlets.
We recommend using good-quality coaxial cable and connectors to maintain RF screening integrity and minimise interference.
