21 TIPS FOR ACHIEVING OPTIMUM PERFORMANCE Maintain a line of sight between the transmitter and receiver antennas. Avoid placing transmitter and receiver where metal or other dense materials may be present. Avoid placing the receiver near computers or other RF generating equipment such as CD players, DA T machines, and digital signal processors.
