I am want to develop a network of AIS receivers with coverage of the
US inland waterways(miss, Ohio, Illinois rivers and the gulf).
Searching the web mostly results in sites targeted for cell phone
carriers. Does anyone know of any sites that would be more appropriate
for this type of need? How do locate sites/towers to be used for
repeaters for example?

Ideally well located amateur towers would probably be best.

Thanks in Advance.
