Installation Instructions
Congratulations on the purchase of your high gain digital aerial. The aerial is ideal for the reception of all available signals in weak and fringe areas.
The aerial is of particularly robust construction to ensure a long operating life.
For optimum results install the aerial using double screened CAI approved digital coax cable and screened coax outlets. You will need to fit the coax cable with an F type connector to connect to the aerial balun.
