Cautions and Warnings Concerning Use 1) The G-450XL has been designed to rotate antenna masts measuring from 48 mm to 50mm in diameter. We recommend that only
6、 masts in that diameter range be used. 2) Do not reverse the antenna movement suddenly, as the internal mechanism will undergo excessive stress. 3) Operate the rotator no longer than five minutes continuously. While you can operate it for as long as ten minutes, make sure to let the motor rest for a
7、t least ten minutes after that. 4) The inside of the rotator is lubricated with a high-performance grease for long-term lubrication. Under normal operating conditions, this lubricant does not need to be changed. 5) Do not transmit near the controller unit with VHP hand-held transceivers, as controll
8、er needle malfunction may result. 5. Mounting Antenna IMPORTANT: The tolerance limits for mounting your antenna vary to a large extent, depending on the mounting method, geographical location, wind velocity, and antenna height. Take into consideration the special conditions of your area when mountin
9、g the antenna, making adjustments as necessary. PAGES Antenna Rotator Model G-450XL i 1) Pole Mounting (using with optional GC-038 Lower Mast Clamp) Use the following formula to calculate the height restrictions for installing the antenna: (Antenna Wind Loading Area) X (Height in meters) 0.25 (Examp
10、le: An antenna with a wind loading area of 0.4m2 and a mounted height of 0.6m is acceptable, as the product of the two is 0.24.) An antenna with a wind loading area of 0.4m2 can be used if the indicated height is less than 60cm (23.6 inches). IMPOTANT: Keep the weight of the mounted Height antenna u
11、nder 10 kg (22 IDS) for pole mounting. 2) Tower Mounting Make sure that the antenna K coefficient and the wind loading area of the antenna to be installed do not exceed the specified ranges. IMPOTANT: You can more reliable operation if you keep the parameters within 60 percent of the maximum specifi
12、ed ranges. Antenna K Coefficient = Antenna Rotation Radius (in m) X Total Antenna Weight Incl. Mast (in kg) Calculate the rotation radius and antenna weight based on the figures given by the antenna manufacturer.

Installing and Adjusting 1) Use 5-conductor (or 6-conduc
17、tor) cable with a diameter of 0.5mm (#24 AWG). Only use as much cable as you need. NOTE: If the cable exceeds 40m (131ft) in length, increase the diameter to 0.75mm (#22 AWG). 2) Assemble the cable according to the following diagram: Tin the wire with solder. Controller Side Rotator Side Make sure t
18、o insert this first. Make sure to perform the following procedure with the POWER switch in the off position Do not use #1. 3) Connect the round plug to the rotator, and attach the other end to the Rotator Control Cable Jack on the controller, making sure to match the numbers on the pins (use only pi
19、ns #2 to #6). 4) Check the power switch with the cable in this state. Insert the power plug in the wall socket, and turn the POWER switch on. The pilot lamp should light, and the direction indicator will rotate until it reaches the current direction of the rotator. 5) Press the LEFT switch on the co
20、ntroller to turn the rotator counterclock- wise. It will stop automatically. Confirm that the needle of the direction indicator rests exactly on the 0 (N) position. If there is needle error, loosen the screw in the center of the indicator and adjust the needle to 0. 6) Look at the rotator, choosing
21、a point from which to mark its rotation. 7) Next, press the RIGHT switch on the controller to turn the rotator 360 in a clockwise direction, watching the point on the rotator that you chose in step #6. Make sure that the rotator returns to the correct position. Also watch the needle on the direction
