Without knowing \nmore, I suspect the two dishes will work for the 2.4 GHz through 10 GHz \nbands. Of course, you will have to design and build suitable feeds for the \ndishes.

One is a smaller dish labeled Dish 500 which I'm guessing is \n> a\n> Ku-Band dish and a larger one labeled Dish Plus which I'm assuming is a\n> C-band dish.
