Nav/Com Capabilities: Antenna
If testing over-the-air i.e. ARTS 7000 antenna to Aircraft under test antenna. For Nav Com functions
connect the antenna part number 123-0239 directly to the antenna port on the top Nav/Com module.
Extend the antenna to its fullest length.
If a remote antenna is required. Please select a suitable cable from the supplied coax cables. Connect
one end of the cable to the antenna port on the top of the Nav/Com module connect the other end to
the antenna tripod adapter. Connect the adapter to the tripod. Attach the Nav/Com Telescoping
antenna to the adapter and position the tripod/antenna in the desired position.
Pulse capabilities Antenna
For Pulse test Functions connect the cable of choice from the cables supplied (best practice is to use the
shortest cable that will work for the test setup) to the antenna port of the Pulse module. Connect the
other end of the cable to the Pulse antenna. Mount the pulse antenna on the supplied tripod. Position
the antenna so that is directly pointing at the antenna to be tested. The optimum position is 6 feet away
from the antenna. Please note the front of the Pulse antenna is embossed with the Laversab name and
logo.
Pulse Antenna Alignment, Reflections and Multi-paths (DME/MODE
S/ADSB/ATCRBS/UAT/TCAS Testing)
The Pulse antenna has been designed to be highly directional. To achieve good test results,
alignment between the Antenna under test and the ARTS 7000 Pulse Antenna must be
accurate. It is recommended to:
1. Mount the antenna on the provided tripod and either use the antenna on the ground or
fix it to a sturdy gantry.
2. Align the center of the Pulse Antenna as accurately as to the antenna under test.
Accuracy is required in both the horizontal and vertical plane.
3. A clear line of sight is required between the antenna under test and the ARTS 7000 a
pulse antenna.
4. Ensure that there are no objects - tool boxes, ground power units, air stairs, gantries,
landing gear etc. in close proximity to the test transmission path. These items can cause
echo and multi-path reflections.
5. Utilize the shortest test cable as possible between the ARTS 7000 and the Pulse
Antenna.
6. Remember to add in the vertical height and horizontal distance from the antenna under
test and the Pulse antenna on the relevant config screen.
