The antenna output is designed for 50 Ohm load; however the transmitter stage is specially protected and 
can handle full power at both open and shorted antenna. 
It is normal to perform range check with antenna removed and 500mW setting.

RF Output power: 500mW 
RF Output connector: SMA female 
RF Input: DIN 4 
The Antenna output is designed for 50 Ohm load. 
The PPM input signal can be either constant frame repeat time, or variable, Positive or Negative 
polarisation. The special double speed Futaba PPM signal is also accepted, Auto detects and auto handle. 
The main PPM signal must contain from 4-12 servo channels, if main PPM signal has under 4ch it will be 
refused. 
Note: Graupner call each way a servo travel for a channel, so in Graupner terms a 24 Channel setting 
handle 12 servos, and is what we call a 12 channel signal.
