Antenna Height measurement made easy

First we must understand the triangle: if the angles are like this 90 and 45
then length A and B are equal.

Then we made this, the PVC tupe is angled 45 degrees

Looking through the PVC tube, and aiming at the antenna top, while holding the water straight

Then looking down to the ground and mount some tape.

Now the distance to the antenna pole is the same as the antenna height, nice and easy.
