i have not tried it out so i don't know if it actually works.
In the case of the quad copter the effects of the aluminum plate outweigh it's benefits as far as the antenna is concerned. The metal plate will throw off the resonance of the GPS antenna. However the electronics may benefit from less induced noise.
