[TowerTalk] Elevated Vertical with No Radials on Metal Roof

[Dudley Chapman]

I second the notion that a non-resonant metal roof that is off the ground
might be a liability rather than an asset for a quarter wave vertical.  The
metal roof would be modeled as a large number of non-resonant radials. 

It occurs to me that the best situation would be a large number of metal
roofing sections all bonded together and placed either on or in the ground.
The difference between this and the elevated roof case is the same
difference as the in-ground vs elevated radial case.

However, the use of sufficient number of radials in the ground would be more
cost effective.
