Do you find it difficult to measure height of your antenna tower? No you do not have to climb along it with a measurement tape, Just build this low cost jig and measure height in 15 minutes.
It is just a PVC tube fitted with a water level meter at exactly 45 degree angle. Then from the knowledge of plain trigonometry, you can easily measure the tower height.
