[Elecraft] Antenna suggestions, resent

[Geoffrey Mackenzie-Kennedy]

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,
