3) Use an angular tester to check whether the antenna axis is perpendicular to the
horizontal plane. If the error is equal to or greater than !1ÿ, adjust and re-fasten it.
4) Tighten the antenna until the antenna cannot be moved by any hand pull or push.
5) Make the waterproof curve of the jumper, lay and bind the jumper along the
cross bar of the support using black cable ties, and cut off the extra tail of the
cable ties.
Caution
The jumpers shall bend in a natural manner. The bending radius shall be 20 times longer than the
jumper diameter. The cable ties shall be wound in the same way. When cutting the cable ties, there shall
be a slack of 5-10 mm left lest the cable ties fall off the jumper due to temperature change.
