M ODEL 5503-5M: F ROM E-M ODE TO H-M ODE
When moving the elements up and down on the
carrier, maintain the same level at all times to
avoid bending or damaging the elements.
Following are the steps to rotate the antenna elements from E-mode to H-mode:
1. While holding the element, unscrew the bolt farthest from the upright
element that holds the frame in position.
2. Let the element rotate 90 degrees until it rests in the U-shaped receptacle
on the upright element.
3. Tighten the bolt to hold the element in position.
