[Elecraft] Antenna suggestions, resent

Hello, 

The way I model the ugly stuff is too use the end range of the ground type and see the effect.  Depending on the antenna model, AGL etc.  The difference can be minor or major.  But I use that to see if I am going to have a problem.

Mel, K6KBE

Hello Vic,

If you have not done this already, it would be wise to include in any model 
all nearby metallic objects such as gutters, downpipes, etc, *before* you 
cut any wire.  Such objects can have a profound effect on the horizontal or 
vertical pattern (or both) of an antenna, as I am sure you know.  If the 
surface of the roof is metal, then a metal grid can be used to represent the 
roof.  If the roof is made of concrete, brick or stone, the roof becomes 
more difficult to model.  I am not certain that I know how to model 
concrete, brick or stone objects correctly.

73,
