On my super sport the comm ant is mounted on the provided plate on top
just behind the turtle deck. The transponder ant is a stub/ball mounted on
the existing plate just behind and below the header tank. The ads-b ant is
a blade type mounted on a fabricated ground plane about mid way between the aft end of the baggage compartment and the leading edge of the horz stabilizer on the underside of the aircraft. The elt ant is mounted inside the vertical stabilizer above the horz stab. All work well.
The ahrs for the Advanced 5600 is mounted in the right wing second bay in from the tip. No apparent interference from any electrical system operation. The angle of attack ports are installed in the left wing in bay before the tip. Also works well. The AOA system is the only way to go.
It allows very good short field t/o and landings with good warning of critical angle of attack.
