The antennas in the figure below are horizontally polarized:
Test Different Power Levels
CTI panel antennas add gain (power) to the broadcast signal and also focus the radio energy
directionally. Both effects tend to deliver more of the radio signal to the desired target, so you
may not need to operate your transmitter at the highest setting. In some installations, system
fidelity
may improve
at lower broadcast power settings. In settings where more than one system
is in use, lower broadcast power settings will reduce inter-system interference.
Using Panel Antennas in Combination with Omni-Directional Antennas
Sometimes an installation will not lend itself to panel-to-panel antenna configuration, such as a
system in which there is a single transmitter broadcasting to receivers located far apart from
each other, so that the receivers could not all be within the beam angle of the transmitter’s panel
antenna. In setups like this, the system may still benefit from using panel antennas on the
receivers and an omni-directional antenna on the transmitter. Using panels on the receivers will
increase their range and limit their susceptibility to radio interference from other sources located
outside of the beam of their panel antennas.
Many of the same setup techniques will work with omni-to-panel antenna systems that work with
panel-to-panel systems:
•
Mount the antennas with direct line of sight
•
Adjust height and rotation to optimize performance
•
Avoid RF obstacles
Elevate the antennas above the ground, but leave clearance for other reflective surfaces
indoors.
