Diode for Radio Power

We have fried our share of Dlinks because of reverse polarity of the power connector. Any thoughts on putting a diode in the power cord to prevent current in the event of reverse polarity?

1) Anything in the rules that would prevent that (alter the power path, custom circuit to supply power, etc.)?

2) Is the voltage drop across the diode a problem? I think Schottky diodes have a 0.40 volt drop.
