Garmin G3X components needed

[Michaels kitfox]

I am trying to find out what specific equipment is needed along with the Garmin G3X for VFR flight and to have ADS-b out and in? I already own the GSA-28 servos and GMC 305, GTR200 radio, Rami AV-11 antenna, and the GMU11 magnetometer. I know that I will need GPS and COMM antennas but I would like to know which specific ones. What other components do I need to put the system together? Obviously I am new to this and this is the first aircraft that I have built and will get my pilots license in.

Thank you,
Michael

For the WAAS GPS I have the GA35 connected to the GTX345 ADSB in and out transponder. I will be purchasing the GA26C portable GPS puck antenna as a redundant antenna that Garmin recommends that I put on one of my GDUs. I don't recall what VHF antenna I have but wish I had done what others are doing with the Vertical Stabilizer mounted Antenna. They are getting good results with that.
Depending on the engine you are using you may need some senders of some kind. I needed a fuel pressure sender for my 912iS. All the other senders were included in the 912iS purchase.

Thank you for the response. I have looked at the GTX345 seems to be a little more than I need and is $5000. Is there a remote mounted system for ADS-b (in/out) by Garmin that is a little less money?

Garmin GTX 45R is a remote-mount in/out ADS-B compliant transponder for use with G3X.

Thank you,
Do you know what Position Source GPS device would need to go along with the GTX 45R?

From the Garmin website:
The extra-precise GPS position reference required for ADS-B can be provided by a GTN 650/750 navigator, GNS series WAAS navigator (i.e. GNS 430/530)or a GPS 20A ADS-B position source.
