You can read about my glareshield installation on my webpage
https://sites.google.com/site/threeu...flarm-antennas
With my side-hinged canopy, ejection is not a problem, but in any way, in my installation, the 2 antennas are just protruding through the glareshield and not attached to the glareshield at all.

My PF brick is feeding the Trig TT21 for ADS-B out and the Ipaq310/LK8000 for improved GPS data, barometric data and Flarm data on the flight computer.

The configuration file is loaded on a USB memory stick and uploaded once at power-up.

Try to keep your antennas above all metal objects, like instrument boxes, panel frame, etc.
