An LPDA (log-periodic dipole array) antenna is an assembly of dipole elements, with each dipole element on the boom longer than the one in front of it, giving the antenna a triangular shape (see Figure 4).

it has many dipole elements of different lengths, an LPDA antenna can transmit and receive across a wide range of frequencies. ... It's a narrow-bandwidth antenna. An LPDA antenna is designed to operate in a wide frequency range. with lower gain. It's a wide-bandwidth (or “wideband”) antenna.Gleam light India renowned manufacturer of the best quality LPDA Antenna operates in the 800-2500 Mhz & 700-2700Mhz GHz & provides 9/12 dbi gain. The antenna offers the N female connector guaranteeing wider compatibility.

In radio communication, an omnidirectional antenna is a class of antenna which radiates equal radio power in all directions perpendicular to an axis (azimuthal directions), with power varying with angle to the axis (elevation angle), declining to zero on the axis.An omnidirectional antenna radiates radio wave power uniformly in all directions in one plane, with the radiated power decreasing against elevation angles above or below the plane, dropping to zero on the antenna''s axis, and producing a “doughnut-shaped” radiation pattern, as shown in Fig. 2.

HF communications: Log periodic antenna arrays are often used for diplomatic traffic on the HF bands. Log periodic antennas perform well because embassies and other similar users will need to operate over a wide selection of frequencies in the HF bands, and it is often only feasible to have one antenna.
