The LPDA has several dipoles arranged in echelon and criss-cross fed from the front. The name comes from the geometric growth, which is logarithmic.
This is a very wideband antenna of medium gain. Usually only about three of the dipoles are carrying much current. The other elements are mostly inactive. As frequency increases, the active elements
