3.5.1.2

Antenna Separation from Existing Antennas and Obstructions

The following is intended to provide general guidance to the installer when analyzing

antenna placement options on the aircraft and describes minimum edge-to-edge

separation criteria from existing antennas or obstructions such as drain masts. It is

strongly recommended that the Installer always consult with WSS Product Support

during this analysis phase to help in determining the most suitable locations and to

discuss any deviations from this guidance that may be necessary. The following

provides physical recommendations based upon antenna physical characteristics.

Please consult with WSS Product Support regarding any additional, specific

separation requirements that may need to be considered based upon RF interference

for aircraft operations systems.

FDQ Separation Distance

HPB Separation Distance

Antenna or Obstruction

≤ 4” High

12 inches edge-to-edge

Antenna or Obstruction

> 4” High

18 inches edge-to-edge

NOTE - All distances as measured directly between the baseplate of the

antennas against the aircraft fuselage.

Where possible it is recommended that the HPB antenna be installed such that the

closest antennas and obstructions are located within a 60-degree area Forward or Aft of

the HPB antenna as shown in Figure 3.5.1.2-2, top down view of antenna locations. For

installations where a deviation must be considered, please contact WSS Product

Support for assistance in evaluating other locations for consideration.
