SV-XPNDR-26X Installation, Configuration, and TestingGarmin proprietary ADS-B protocol (compatibility not verified)Some of the protocols listed above may not contain all the required data for a compliant ADS-Bmessage, depending on the intended airspace regulations. Further information can be found inthe GPS Data section under the Transponder Settings of this chapter.(US-Only) Direct Serial GPS Position Input for FAA 2020 ADS-B Out Mandate ComplianceTo comply with the 2020 ADS-B Out Mandate in the US, the GPS position used for ADS-B Outposition reports must be directly connected to a suitable ADS-B Out device (in this case, the SV-XPNDR-26X), and, that GPS must meet TSO C166b. DO NOT connect any GPS (includingSkyView’s own GPS outputs) that does not meet TSO C166b directly to the transponder.It is important to note that in the US, the ADS-B Out “mandate” and its associated GPSrequirements do not go into effect until 2020. If you do not already have an appropriatelyTSO’d WAAS IFR GPS in the aircraft, you may continue to leave this Direct Serial unconnectedfor the time being. Instead SkyView has the capability to send its GPS position to the SV-XPNDR-26X using the SkyViewSV-XPNDR-26X serial connectivity (see the GPS DATA option under the“Transponder-Related SkyView Display Settings” in this section for more information aboutconfiguring this option). Although SkyView’s GPS output does not meet the 2020 requirements,it can be used until then to “wake up” the ADS-B ground stations so that they report back traffictargets around your aircraft’s position.Antenna InstallationThe antenna should be installed according to the manufacturer’s instructions.The following considerations should be taken into account when siting the antenna:The antenna should be well removed from any projections, the engine(s) andpropeller(s). It should also be well removed from landing gear doors, access doors orothers openings which will break the ground plane for the antenna.The antenna should be mounted on the bottom surface of the aircraft and in a verticalposition when the aircraft is in level flight.Avoid mounting the antenna within 3 feet of the ADF sense antenna or any COMMantenna and 6 feet from the transponder to the DME antenna.Where practical, plan the antenna location to keep the cable lengths as short as possibleand avoid sharp bends in the cable to minimize the VSWR (voltage standing wave ratio).Electrical connection to the antenna should be protected to avoid loss of efficiency as a resultof the presence of liquids or moisture. All antenna feeders shall be installed in such a way that aminimum of RF energy is radiated inside the aircraft.SkyView System Installation Guide - Revision O 11-11
