This discussion got me thinking that besides a transponder antenna I needed another antenna for ADS-B in/out. Turns out my thinking was correct for the Garmin equipment I am installing. The GNX 375 is a combination IFR GPS navigator and mode S transponder with ADS-B in/out.

Rod,
The transponder antenna is all that is needed for ADS-B. You will need a GA 35 GPS antenna for the 375 however.
Please let us know if you have any other questions.
Best regards,

I am about to purchase a G3X system and want to include the GNX 375 in the system. Besides the transponder antenna, what kind of antenna do I need for ADS-B in/out?
Thanks,
Rod

Yes.
My posting last night had some problems
with cut-n-paste of the pictures. I've
formalized the posting as an article
and added some data on the effects
of increasing the width of a 1/4-wave
radiator.
See:

I'll suggest that the term "dual-band"
in the cited advertisement is mis-leading.
I think I would call it a "wide-band"
antenna suited for a variety of services
within its performance bandwidth.
