CAUTION   
DO NOT allow the pole or other surfaces to extend higher than the underside of the 
antenna. Such a condition would impair signal reception. 
The most important consideration in selecting a position for the 
antenna is the presence of objects which obscure the sky or horizon. 
Where possible, there should be no obstruction to a full view of the sky. 
Overhead wires and other very narrow obstructions may be considered 
as invisible to the signals, provided that they are a few meters away. 
Large flat surfaces can decrease performance of the receiver.
