1.4.3 Cabling

Signal delay differences can occur due to differences in the cable length from the transmitter to each radiator. In order to

minimize the risk of black spots, use equal cable length from transmitter to radiator if possible (see Figure 1.23).

Figure 1.23 Radiators with equal cable length

When radiators are loop-through connected, the cabling between each radiator and the transmitter should be as symmetrical as

possible (see Figure 1.24 and Figure 1.25). The differences in cable signal delays can be compensated with the signal delay

compensation switches on the radiators.
