Parabolic Antenna
Well, the normal Antenna transmits the signal in all direction, but is it possible to replace this with some type of parabolic shape to achieve or concentrate the signal to a specific area?  Because in the case of RC Submarine, can this type of modification will help to increase the gain of radio signal.....

a small input..

the antenna no matter is a very important device in radio transmission but the antenna is of no use with a  good RF Radio behind it...

the grid antenna has a small aperture compared to panel antenna while a omni has it going with a merry go round signal.....

in case anyone needs any more info on the antenna's and the RF paths please feel free to PM me or share your query on this forum and I will be happy to help...
