MTP 312.5 

- 

5000k         Installation of the radio transmitter on a shaft

 

For rotating application we normal recommend an inductive

 

transmission 

 

instead of radio transmission!

 

 

Cable Red = +5V 

Cable Black = GND (Ground) 

Cable Brown = PCM In 

Cable White =  Wire antenna  

 

All cable connections should be soldered. 

 

 
 
 
 
 
 
 
 

 

 

 

This coaxial adapter (

Tx-TNC-

adapter

) makes it 

possible to connect an antenna with TNC connector for 

point to point applications. (option) 

 

Transmitting antenna 0dB with magnetic foot (option) 

 

 

Installation of quad antennas (4x):

 

Install about 1m far from shaft,  

1x up and 1x down side and  

1x left and 1x right side 

About 1m distance to each other antenna 

Installation of diversity antennas (2x):

 

Install about 1m far from shaft,  

1x up and 1x down side 

Mount the cable antenna exactly one 

winding around the shaft and fix all with 3 

windings mounting tape – finish! 

 

The cable antenna can extend or shorten 

depending upon requires! (Isolate the 

solder connection, if you extend the wire 

antenna cable!)
