That is pretty cool. They did traffic on the PFD just like
Chelton did. It's nice because if it shows up on the PFD,
you know it's right in front of you somewhere.

I have to say the images of the traffic on the site do not do the
traffic system justice as the extreme zoom feature of the MFD allows you
to really pick out individual targets of most concern.

The Navworx product is a UAT product and uses a frequency of 978 Mhz.
This is different than the frequency used by Mode C or S transponders
(1090 Mhz). There should be not "seeing" issue between UAT and the
transponder antenna.
Top antenna is GPS antenna and bottom antenna is UAT antenna to
communicate with ground stations and other aircraft.

The two antennas required I believe are the GPS and the fin DME/transponder
antenna My understanding was that the extra DME antenna was for top/bottom
coverage. As a former MRX user and Zaon XRX tester; I found that sometimes
the transponder antennas on the bottom of an aircraft prevented the system
from "seeing" the traffic

Of course there could be a "seeing" issue if the location of the two antennas is such that the transmitter of one will swamp the receiver of the other. This situation can arise even if the frequencies are different.
We need to review the installation requirements of all components and antennas relative to one another before cutting precious holes in our fuselage.
