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. |
• | Avoid placing the receiver in the bottom of an equipment rack unless the antennas are remotely located. |
• | Use the proper receiver antennas. |
• | Point the receiver antenna tips away from each other at a 45° angle from vertical, and keep them away from |
| large metal objects. |
• | Do not obstruct the receiver antennas. |
• | Use the proper cable when remotely locating receiver antennas. For best performance, use Shure UA825 or |
| UA850 low loss coaxial antenna cable, or 50 Ω low loss cable such as RG8. |
•Use Shure UA820 1/2 Wave Antenna and UA830 Active Remote Antenna Kits, along with Shure UA845 Anten- na Distribution System for remote antenna placement.
•Mount diversity antennas at least 1/4 wave apart. This can be achieved by remote placement of one or both 1/2 wave antennas using Shure UA825 or UA850 low loss coaxial cable and a Shure UA830 Active Remote Anten- na Kit in conjunction with a Shure Antenna Distribution System. For multiple system installations, use the Shure UA845 Antenna/Power Distribution System.
