That's not what I meant was wrong. The IC is basically two switches, one at each side of the motor, turning one on makes the motor rotate one direction, turning the other on makes it rotate the other way. The protection circuit is there if needed to ensure it isn't possible to turn both switches on at the same time as this would damage the IC.
Your problem is where you get the signal from to control the IC. You must use a radio transmitter and receiver but yur diagram shows neither. Your transmitter would produce just a few cycles of signal at an extremely low frequency and even then only if you used a huge inductor for the coil. Your receiver has the same problem and it also has no way to distinguish beteen forward and reverse control signals. Even to get a reasonable few cycles of RF an assuming an inductor of say 2 Henries, the frequency would be (f = 1 / 2* pi * sqr(L * C)) or with real figures 1/(6.28 * sqrt(2 * 1000^10-6)) = 3.56Hz. So the transmit and receive antennas would ideally be quarter wavelength long which is about 13,170 miles long each. This is probably not what you wanted!
What you need is a proper RF data transmitter and receiver. Encode the data at the transmitter so it carries information on which way the motor is to turn and decode it at the receiver into one of two control signals, connect one control signal to one input of the IC and the other control signal to the other input. It is a MUCH more practical solution and saves enough antenna wire to wrap around the Earth twice as well!
