Fixing

Methods for mounting the amplifier are illustrated in Figs. 5 to 7. The cable tie fixing is intended to support the weight of the amplifier only. Cables should be taped to the mast at intervals of approximately 400 mm to ensure that their weight is adequately supported.

Being fully screened, these amplifiers will not be affected by proximity to antennas. However clearance of not less than 300 mm from the nearest part of an antenna should be observed to avoid degrading the antenna’s performance.

Signal connections

To preserve RF screening integrity the signal connections to the amplifier should be made using good quality coaxial cable and connectors. This is particularly important with DTT to minimise the ingress of impulsive electrical interference. The use of cable ‘benchmarked’ under the CAI scheme is recommended.

Crimp ‘F’ connectors, used in accordance with the manufacturer’s instructions, will give the best results. The importance of achieving sound braid connections cannot be over-stressed.

System earth bonding

Earth bonding terminals are provided on the amplifier castings for use where necessary.

Distribution systems supplying signals to more than one household should comply with the safety requirements of BS EN 50083-1. This effectively requires the system to be earth bonded. (The use of isolated outlet plates is no longer recommended since they compromise screening integrity and allow ingress of interference.)
