I want to build a simple low pass filter with a cut off frequency of 30Mhz that can handle about 500 watts. I've downloaded a couple of applications to help calculate the design specs and also used this site:

I'm not sure where to start on the inductor design. I know you can do this with a simple coil, but how do I figure out the dimension/turns of the coil to achieve the recomended inductance value? Also, I have to take the necessary power handling capabilities of the caps and inductor into consideration.

I'm sure this is simpler than I'm making it to be, so if someone can point me in the right direction, I'd appreciate it.
