4.1.4 Height of antenna
As is the case with all antennas, the rule of thumb is “the higher the
better”. You should attempt to make the lowest point of the loop at
least 10 feet (3mtr) above ground.
4.1.5 Inside or outside
If possible, the antenna should be located outside and clear of any
structures for maximum effectiveness. If you find this impossible, and
you must locate the antenna inside, consider the following:
• Ensure that the antenna will be at least 4 inches (10cm.)
away from any larger metal objects such as a corner
column or window support.
• Does the ceiling or roof of the room contain metal mate-
rial? This can have a negative effect on the performance
of the antenna.
• Is there any metal within the outside walls of the build-
ing? This can also have a negative effect.
4.1.6 Environment
Your physical environment can influence how you mount STEALTH.
For example, in a rainy area, an outside mounted antenna would need
to be mounted as high as possible to avoid interaction with the wet
ground. In a desert, where it is dry, this would be less of a considera-
tion.
4.2 So what should I do?
The above descriptions are the ideal situations and may not always be
obtainable. You should make every effort to install the antenna in an
optimum way.
Although a square or rectangular antenna loop is generally more ef-
fective, a triangular loop can also be used. If necessary, shape the an-
tenna as two-turn or three-turn loop and lay it on an inside floor. It
will not be as efficient as possible but you should be able to conduct
effective communications.
