TV 585-698MHz band antenna dimensions required?

sir,
I need dimensions and shape of antenna which radiates at TV band i.e 585-698MHz band.
please help me asap.

The yagi antenna is popular and easy to construct. The link below has a calculator for dimensions (3-element type). I once built a yagi from wood sticks and copper wires.

Why don't you just use a normal UHF TV antenna ?
It will work transmitting just as well as receiving.
