I always thought 1/4 length was easier because you can make one easily from 1/1 length
by breaking in half exactly two times. And then you have 4, so more economic too. A dipole is made from two quarterwaves. An odd quarterwave is easy to match to. Any other length needs a matching network of some kind. Gain comes about from directing the RF in some directions. This can be one direction like a beam, or omnidirectional with something more complicated then a simple quarterwave antenna. Tell your instructor he needs some more instruction.
