Default The WellBrook Active Loop Antenna ALA 100

Miso,

With the larger WellBrook ALA 100 Loop Antenna you are
generally limited to a Fixed Position and therefore can not
use it to Null-Out the Local Noise.

The WellBrook Active Loop Antenna ALA 100 is a Large
Aperture Antenna designed to provide improved performance
compared to traditional Active and Passive Antennas.

-Note- At Sixty Feet (60') of Wire a Loop Antenna is a
relatively Long Wire Antenna in the Shape of a Loop. )

HORIZONTAL OR VERTICAL :
Will the WellBrook Active Loop Antenna ALA 100 work
as well Flat {Horizontal} as well Upright {Vertical} ? ? ?

TWIN LOOP ANTENNA ELEMENT :
I have consider the possibility of using a WellBrook ALA100
that would be suspended up 25 Feet from a Tree Limb.
The Loop would be a Diamond Shape with a Ten Foot (10')
pieceof PVC Pipe as a Cross-Arm using Two continous
30 Foot Wire Loops spaced at about 18 Inches apart. This
would allow the Loop to be Manually Positioned to Null-Out
any Local Noise or to Point the Loop in the general direction
of a Target Signal Area.
