G-1090 receiver installation
Finding the best location
The INVOLI support team can assist with the selection of the best location points for the receivers. It is particularly important if the receivers will work in the cluster for the multilateration. If the receiver is already operational, it is possible to perform an evaluation of its reception performance and decide if the installation is good enough or should be modified.
Pole mounting
Follow the instructions below to install the G-1090 Air traffic receiver over a pole:
1. Fix the included cross bracket on the bottom of the enclosure with four M6x12 bolts.
2. Place two clamp pieces around the pole and tighten them with the included M6x110 bolts, washers, and nuts.
3. Connect the pole clamp and the cross bracket by securing the last piece of the mounting kit in place using M6x30 bolts, washers, and nuts.
If needed, the G-1090 can be mounted on a horizontal pole without the 90° angle converter part.
Antenna mounting
The picture below shows the top of the G-1090 air traffic receiver with marked antenna ports. For the Flarm or UAT options, please see the next article, which shows the pictures with mounted Flarm and UAT antennas.
Screw the GPS antenna and the 1090 MHz antenna on their N connectors, according to indications. For a 1090 MHz antenna, use a male-to-male N-type adapter. The picture below shows properly installed antennas:
Installation documentation
It is recommended to take several photos documenting each installation from different angles. The pictures can help troubleshoot later if the installation is not performing as expected.
