Is a 6 foot height increase worth the effort?

@VivPike
Fully agree with @Dxista and @belzybob.

1. If antenna cannot “see” horizon in most or some directions, every ft. of height increase improves range.

2. To know if your antenna REALLY “sees” the horizon in all (or most) directions, first use following link to create a reference to judge if you have already achieved maximum possible range with your antenna location and current height. If your actual range is equal or somewhat more than the one predicted by this method, than your antenna “sees” the horizon in those directions.

   You can also create another one using current height + 6 ft.

   What is the Maximum Range I can Get?

3. If you come to conclusion that your antenna REALLY “sees” the horizon in all directions, increasing height will give negligible benefit, while the effort and cost may be substantial. However, there is no harm in increasing height if too much complications, cost, and effort are not involved.

   Below is an example table showing this phenomenon on a level terrain (i.e. no surrounding hills or steeply rising terrain) and provided antenna can see horizon on ALL these heights.
