What’s an LPDA antenna?

An LPDA (log-periodic dipole array) antenna is an assembly of dipole elements, with each element longer than the one in front of it, giving the antenna a triangular shape. Because it has many dipole elements of different lengths, an LPDA antenna can transmit and receive across the entire range of frequencies used by cellular carriers (617–4000 MHz).
