R User and Installation Guide Step 3 Placing the amplifier For best reception, we recommend that the amplifier be placed within the line of sight from the transmitter. If possible, the amplifier should be placed right side up with its front toward the transmitter. Example 1 below shows the optimum placement of the amplifier. If no line of sight is possible, place the amplifier such that there is the minimum possible number of walls and obstacles between the transmitter and amplifier.
