What antennae do I need.
Building an IFR machine and am planning dual G3X, G5, and GTN750. Aside from the WAAS antenna which I believe is the GA35, what other GPS antennae would be recommended?

The only thing that could be added to Bob's list is an antenna for a marker beacon, if your audio panel supports one. Roll your own with a 39" wire in a wingtip.

Thanks guys. Four GPS units Bob? Aside from the 35 which goes up top, where did you locate the others? I was thinking I would put one on the undersurface of the overhead console. Glare shield for other two?

The G5 should have a GA26 as well.

antenna
"...Four GPS units Bob?..."
The GA35 is for the GTN650
The GA57X is for the GDL51R XM/GPS
The GA26C's are for the GDUs. These will go on the glare shield.
I will have to ask Stein about the GA26C for the G5...

You don?t really need the GPS antenna portion of the GA57X. The GDL51R will get the GPS info from the GDU (according to Garmin). I used the GPS portion of the 57X for the G5, and used the two pucks on the glareshield for the GDUs.

I put the 35 and 57X on top of the cabin, the two pucks on the glareshield. I know... I know... my plane will fall out of the sky because i penetrated the cabin top

If you’re not going buying a G3X with the built-in XM receiver, you can use a GA 56, which can be had used for about $50 from eBay. It’s the same as a 57 without XM.
I have a GA 35 for my GTN and then the GA 56 for the G5. The G3X will get GPS signal from either the GTN via GAD 29 or G5 via CAN bus, so you do not need a separate antenna just for that.
BTW, if you use Garmin antennas, you can mount them both 6” apart (CoC) side by side.

At least one of the G3X screens needs it's own antenna, for dual screens I use one for each.
