I don't think that 25 mW are allowed in the FM band. Preliminary test show about 1/4 a mile with just 1 mW and a simple dipole antenna...

About 10 years ago I use to work in WSAN, a full power(50 Kw ) station. In one remote site we have a 1 watt translator with a Comet 5/8 wave antenna installed in "Banco Popular" main building (about 200 feet tall building) with a 20 feet pole. Our coverage was at that moment about 5 to 8 miles ...

About 2 miles with a high tower...

Does someone know how much power I can use in the FM band and still complying with Part 15.239 of the FCC (250μV/m at 3m)?

Unless you are ready to pay millions for an establish commercial station, there is nothing you can do (in NY)...

Other alternative is to look for an available channel in other place!!!

What I mean is a NEW permit for contruction of a NEW radio station...

Sorry to say this, but I don't think that there are any available channels in the NY area...
