CHAPTER 3: PROGRAMMING INSTRUCTIONS

Typical Antenna Configuration

Base station antenna configurations may vary from site to site depending on the type of mounting

structure, the presence of existing antennas, mounting structure loading limitations, etc. The following

information is provided as a guideline for a typical scenario.

Figure 6: Typical Antenna Configuration

An otpimal antenna mounting configuration is shown in the figure above. The transmit antenna and

receive antennas are located at different elevations. This vertical separation provides the greatest degree

of isolation between transmit and receive antennas. The three (3) receive antennas are mounted at the

same elevation and are oriented in a 120 degree triangular pattern. A triangular orientation of the receive

antennas provides optimal diversity performance in an omnidirectional pattern.



The greater the separation between receive antennas, the greater the diversity gain; therefore,

the distance between antennas should be made as great as is practical.

In the event only two (2) receive antennas are used (i.e. a dual receiver diversity reception system), the

receive antennas should be mounted in a broadside orientation with respect to the radio coverage area.



To prevent the antenna’s radiation pattern from becoming distorted, the immediate area

surrounding each antenna should be kept free from conductive objects (i.e. other antennas, guy

wires, or the tower structure itself). The amount of clear area required to prevent pattern distorion

is equal to the antenna’s near-field exclusion.

CHAPTER 3: PROGRAMMING INSTRUCTIONS Near-Field Exclusion Zone The near-field exclusion zone (NFEZ) is the required distance between antennas to any other surfaces to improve transmit and receive performance. The large radio frequency field that builts up around the antenna upon transmitting is essential for proper data transmission. It can be severely corrupted by metal objects in the NFEZ.
