Getting the “best and the cheapest” all in one order can be done, but mostly by someone who knows a lot about the technology.
Several members of this board know plenty about the technology and, like Radio8Z who just posted before me, could guide you toward the objective, but hard physical facts are required before a plan can be written.
How large is the campus, how many buildings are there, what is the architecture of those structures, and this is impotant… where will the potential listeners be located?
If you want to get signals into several buildings there is carrier current for AM and cable for FM.
Equipment can often be found at basement prices on eBay, but watch out, not all of it is “the best”.
Radio8Z made an important point…. things should start small and grow based on experiment and discovery. An educational process indeed.
If it were me I would use all available outlets…. AM, FM, several antenna locations, carrier current, cable, the works.
Most of all, don’t give up on the idea. It is VERY worth doing!
