Sv GPS 2020 antenna

[Doug94]

If I replace the current SV GPS antenna with this new one and add the ADSB module, do I need to run a seperate antenna for the ADSB or will this antenna serve that pupose?

there are two antennas for ADS-B
1) 2020 sky facing GPS
2) transponder type antenna facing ground.
So if asking will this serve the ADS-B requirement for GPS, yes it will and no other GPS is needed.

Actually, there are 3 (at least on mine ...) - GPS, XPNDR, and ADS-B antenna.

good clarity!
3 - current transponder
2- ADS_B antenna on bottom that uses the same TYPE of antenna as the transponder
1- ADS_B compliant GPS antenna (puck)

since I already have the gps antenna and I have two displays
can I keep the old gps antenna installed as gps #2 and simply
add the new one to my system?

You can if you have a spare serial port. That also gets you a backup GPS source.
