This may be a question for Matt B or Stein-
I'm strongly considering a dual Garmin G3X setup, with a GDU375 and a GDU370, which will be connected to a Garmin GNS430W and TruTrak DFII VSGV. Since these GDU's will be panel mounted, what type and number of external antennas will I need for the GDU's? Currently, I have the 430W GPS antenna mounted inside the cockpit on top of the instrument panel.
I have seen where some recommend a separate antenna for each connection on the back of the GDU's, ie 2 GPS and 1 XM, versus a single antenna. Garmin also makes a combination GPS/XM antenna, so could this antenna be used? I think that I read where the GDU's can share GPS information, but does this mean a splitter in the GPS antenna line or sharing via a data link?
Thanks.
