mounted directly below the baggage compartment. These antennas are
connected to the two VHF communication transceivers contained in the
Integrated Avionics Units.
The optional blade-type DME antenna is mounted on the airplane under-
side just aft, right of the firewall.
A sled-type marker beacon antenna is mounted below the baggage
compartment floor and provides a signal to the marker beacon receiver
located in the audio panel. If the optional air conditioning system is
installed, this antenna is located below the baggage floor inside of the
airplane.
The transponder antenna is located on the bottom side of the airplane, just
aft of the baggage compartment bulkhead on the RH side of the airplane.

grated Avionics Units.
The optional Traffic System antenna is mounted just above the

antenna is located on the bottom RH side of the airplane just forward of the
baggage compartment.
