PERFORMANCE
There is no change to the airplane performance when this avionic
equipment is installed. However, the installation of an externally mounted
antenna or several related external antennas, will result in a minor
reduction in cruise performance.

GENERAL
The Cessna 300 Transponder (Type RT-359A), shown in Figure 1, is the
airborne component of an Air Traffic Control Radar Beacon System
( ATCRBS). The transponder enables the ATC ground controller to "see"
and identify the aircraft, while in flight, on the control center's radarscope
more readily.
The Cessna 300 Transponder consists of a panel-mounted unit and an
externally mounted antenna. The transponder receives interrogating
pulse signals on 1030 MHz and transmits coded pulse-train reply signals
on 1090 MHz. It is capable of replying to Mode A (aircraft identification)
and Mode C (altitude reporting) interrogations on a selective reply basis
on any of 4,096 information code selections. When an optional panel-
mounted EA-401A Encoding Altimeter (not part of a standard 300 Trans-
ponder system) is included in the avionic configuration, the transponder
can provide altitude reporting in 100-foot increments between -1000 and
+35,000 feet.
All Cessna 300 Transponder operating controls, with the exception of
the optional altitude encoder's altimeter setting knob, are located on the
front panel of the unit. The altimeter setting knob is located on the
encoding altimeter. Functions of the operating controls are described in
Figure 1.
