[TowerTalk] Tower height increments

[WarrenWolff at aol.com]

Greeting fellow TTalkers,
 
I have an interesting question.
 
Does anyone know what happens to the radiation lobes for a 40  meter yagi 
when it height above the ground is changed from 69 feet to 79  feet?  It
boils down to whether or not the extra 10 feet is really worth  it --- or the
potential hassle from a City Engineer for the extra 10  feet.
