I thought a bit more about this… while a beachfront/salt marsh location might be ideal for building an international broadcast facility, if you were building a station for domestic Haitian audiences you would probably prefer a high location reasonably far from the sea and its corrosive effects. Or perhaps you might design a tower primarily as a support structure and utilize easily replaceable vertical dipoles with coated wire as the radiators. Without extensive maintenance a tower might last a relatively short period of time and have conductivity issues.
