CommScope DB5091-3 Manuals

1. After removing the antenna from the shipping package, inspect contents to make sure all parts are on hand and that there is no physical damage. 2. Inspect the antenna output connection to determine that it matches with the end of the station transmission line. 3. Check the antenna label to verify that the frequency to which the antenna has been tuned matches the frequency on which the radio system is to operate. GENERAL INFORMATION 7. After the jumper is attached to the antenna, the connec-tion should be sealed to protect against moisture. Make certain the open drain hole is not covered. INSTALLATION INSTRUCTIONS 1. Attach the heavy duty mounting clamps on the antenna only at the positions labeled: 2. Remove the rubber boot before installation (Figure 1). 3. Pre-assemble as much of the mounting hardware as possible to the antenna while on the ground. If hoisting the antenna to the top of the tower or structure, attach a rope to the mounting hardware at the bottom of the antenna and then make a slip knot loop of the rope at the top of the antenna. The slip knot loop will keep the antenna vertical when hoisting the antenna. For safety, an additional rope can be attached to the bottom of the antenna and be used as a guide by someone else on the ground. 4. Securely attach the antenna to the cell site support. Tighten all hardware using the following torque: 1/2-13 = 516 LBS-IN (58 N-M). 5. Remove and discard the cap plug from the antenna connector. 6. For standard upright mounting (connector end down), remove the drain plug from the connector end of the antenna (labeled “A” in Figure 1), leaving the spike end (labeled “B” in Figure 1) plugged. For installing an antenna in an inverted position (con-nector end up), ensure that the drain hole at the con-nector end (labeled “A” in Figure 1) is plugged and the drain hole on the spike end (labeled “B” in Figure 1) is open. For maximum strength, the mounting clamps should be mounted as far apart as is safely possible. CAUTION: Electrical downtilt models must not be mounted in the inverted position. Doing so will cause the beamtilt to be incorrectly directed upward. Figure 1. Antenna Using DB5091-3 Mounting Kit. WARNING! In the event that a tower top mounting configuration raises the top of the antenna more than 20 feet above the tower top, refer to Section 17 of FAA rules for special lighting requirements. Installation of any antenna near power lines is dangerous. For your safety, follow the antenna installation procedures.
