What characterizes a distribution amplifier on a network design map?

A distribution amplifier is specifically designed to increase the signal strength and distribute it evenly across multiple outputs. This characteristic is crucial in network design as it allows the same quality signal to be sent to multiple locations or devices without significant loss of quality.

The presence of multiple downstream outputs is what fundamentally sets a distribution amplifier apart from other types of amplifiers or devices in the network. This capability ensures that various devices can receive a signal simultaneously, making it an essential component in setups where multiple feeds are necessary, such as in cable television or other broadcasting setups.

In contrast, a single downstream output would characterize a different type of amplification system, while a built-in power inserter is typically a feature of devices that need to supply power to associated equipment but is not a defining characteristic of distribution amplifiers themselves. Additionally, while distribution amplifiers can be installed on trunk lines or in strategic locations throughout a network, they are not restricted to just the main trunk line; they may be placed at various points to optimize signal distribution.
