How to setup antenna on controller/instrument for best radio range

The signal radiating from the radio antennas travels out in all directions when looking down on the antenna, however, from side on there is no signal coming out of the top or the bottom


This means that in order to maximize your radio range the controller antenna should be in the same vertical position as the instrument antenna.

Also line of sight between the antennas is required in order to achieve good communication and maximum radio range. Objects between the antennas create radio shadows that decrease the range and link stability. For example objects like trees and vegetation, buildings and vehicles can create a radio shadow, but also the human body and the equipment.


Mount your 2.4GHz Trimble Empower module furthest from the pole to minimize the radio shadow.
