A simple solution is generally less expensive to build, operate, and maintain. Usually, a simple solution is elegantly satisfying, and yields a superior result.
Take the Allen Telescope Array ultra-wideband front end (Figure 1). In order for a single facility to cover the desired 0.5 - 11.2 GHz bandwidth, a traditional solution would have required about 3 separate feeds and receiver chains and probably a "carousel" to allow them to be automatically switched in or out. This degree of complexity would have been required to receive the signals with high sensitivity and transport them back to the signal processing lab. It also just may not have fit within the space available and would be too costly. A means to receive, amplify and bring back the entire bandwidth at once would be simpler and better. But that had never been done before.
