Antenna Installation

In order to achieve the optimum range or the highest signal strength for the chosen antenna systems then care has to be taken with the choice and deployment

Basic System Installation

Omni-directional antenna - external mounting

For instruments that are deployed fairly close together and in clear line of sight of each other then omni-directional antenna systems will be ideal for data transmission. Omni-directional antenna systems are the simplest install and maintain.

For optimum range mount the antenna clear of any object and about 1 m above the ground. Any change in this deployment will degrade the range and this degradation will depend upon the environmental conditions prevailing

Directional antenna Systems - external mounting

Directional antenna offer increased range for the same transmitted power by restricting the transmitted signal to a specified direction. In order to get the best results it is important to keep the antenna clear of any local metallic objects above the ground. Deploy the antenna about 1.5 m above the ground and make sure any mast system being used is firmly installed.

Ensure that the directional antenna is pointing absolutely at the data logging system antenna and that the polarisation between remote systems is the same ie. Vertical-to-Vertical or Horizontal-to-Horizontal polarisation.

Circular polarised antenna systems are the only type that should be use when systems with mixed polarisation antenna are to be used together.

For optimum range tilt the standard omni-directional antenna 3 deg from the vertical in the directional of the receive unit

Keep the antenna 1m above the ground

and free from any close objects.
