Flat Panel Directional Antennas
Flat panel directional antennas produce hemispherical coverage, spreading away from the mount point at a width of 30 to
180 degrees typically. Concentrating the signal on this smaller area increases system range.

Sector Antennas
Sector antennas are high-gain directional antennas. These cylinders contain a boom supporting thin vertical rods. The
signal propagates off the front of the boom. Note that some signal (back lobes) fall behind the boom. Sector antennas
create higher gain by producing narrower beams (20 – 80 H, 14 – 64 V).
The wide-angle sector antenna is a good Base Station antenna for hilly terrain. It combines a wide opening angle “sector”
with relatively high gain. The mounting brackets allow tilting of the antenna. This antenna also is used when the amount
of traffic in a cell is too high for a single Base Station with an omni-directional antenna. The wide-angle antenna allows
dividing the cell into three sectors that each can be serviced by a Base Station.
