[TowerTalk] How Far from the house not to effect antenna pattern?

[Keith Dutson]

Think of your roof as an extension of the ground.  Keep your antenna about
1/2 wavelength above the roof to keep ground losses and elevated pattern to
a minimum.

Hi Guys,
 
One question I have always had about towers that are placed near the  house
is how much does the house wiring and gutters effect the antenna  radiation
pattern?
 
And if the house has a metal roof ... what effect does  the metal roof have
on the radiation pattern?  I ask because I've been  considering a metal
roof.
 
One thing I have experienced first hand with towers near a house is
increased QRN.  Guess that's a no brainer but it's a factor worth
considering if one has the option to locate the tower a good distance away
from  the house.

I also know, that there are millions (literally) of towers put  within 4-5
feet, if not closer, to homes, with no coupling issues.

I  wouldn't go so far as to say that.

The accurate way to say that would  be....


I also know, that there are millions (literally) of towers put within  4-5
feet, if not closer, to homes, THAT HAVE NEVER SUFFERED SEVERE DAMAGE
...BUT OF COURSE THEY MAY NEVER HAVE BEEN HIT EITHER.

It makes perfect  sense that planting a tower next to the house is
significantly worse than  having it some distance away. Even a small
distance of a few feet is better  than bolted directly to the house.

I think the suggestion of some  spacing is a good one, even if the "required
distance" is a number pulled out  of an area near someone's back  pocket.
