AAT AZIMUTH SCOPE KIT INSTRUCTIONS- RELEASE 1.0
MEASURING AZIMUTH FROM THE FRONT/FACE OF THE ANTENNA
1) Determine which antenna(s) are to be measured. Pace off or measure approximately
200 ft from the tower base along the boresite (radiation centerline. Visually align the
tripod to the antenna and secure the tripod in position.
2) With the antenna located, adjust the magnification by rotating the eyepiece (clockwise
increases magnification) such that the lower front edge of the antenna is easily viewed.
The adjustment knob on the right side of the AZM scope sets the focus. Readjust the
position of the AAT/scope/tripod assembly as necessary.
3) Adjust the AAT/scope/tripod position such that the sides of the antenna are not visible
(antenna is viewed “head-on,” vertically centered in the viewfinder). Align the reticle in
the viewfinder with the bottom edge of the antenna.
4) Power the AAT on. Wait for GPS/AZM signal acquisition.
5) From the AAT Main Menu, choose “Select Orientation.” Set the orientation to “AAT
Faces Front.”
6) Ensure that the AAT is within +/- 1 degree of level in both tilt and roll.
7) From the AAT Main Menu, select “Measure Only”.
8) Verify the antenna position through the viewfinder, ensuring that the antenna is
vertically centered (“head on”) and that the reticle is aligned with the lower edge of the
antenna.
9) Note the AZM value displayed on the AAT. This is the azimuth of the antenna being
measured.
MEASURING AZIMUTH FROM THE BACK EDGE OF THE ANTENNA
Back of the antenna must be readily visible!
1) Determine which antenna(s) are to be measured. Pace off or measure approximately 200 ft
from tower base in-line with the backplane of the antenna (perpendicular to radiation
centerline). Either side of the antenna is acceptable (to the right or left of the radiation
centerline). Visually align the tripod to the backplane of the antenna and secure the tripod
in position.
2) With the antenna located, adjust the magnification by rotating the eyepiece (clockwise
increases magnification) such that the side and antenna lower edge are easily viewed. The
adjustment knob on the right side of the scope housing sets the focus. Adjust the position of
the AAT/scope/tripod assembly as necessary.
