RF INTERFACE 

 

 

The SLR6 modem has a single antenna connector with impedance of 50 ohm.  

 

The output power of the transmitter is adjustable between 0.1, 0.2, 0.5 and 1.0 W. The greatest 

allowable power depends on limits set by local authorities, which should not be exceeded under 

any circumstances. The output power of the transmitter should be set to the smallest possible level, 

which still ensures error free connections under variable conditions. Large output power levels 

using  short  connection  distances  can,  in  the  worst  case,  cause  disturbances  to  the  overall 

operation of the system. 

 

 

 

 

 

 

 

 

 

 

NOTE! 

Setting the radio data modem output power level to that which exceeds the regulations set 

forth by local authorities is strictly forbidden. The setting and/or using of non-approved power 

levels may lead to prosecution. Satel and its distributors are not responsible for any illegal use 

of its radio equipment, and are not responsible in any way of any claims or penalties arising 

from the operation of its radio equipment in ways contradictory to local regulations and/or 

requirements and/or laws.
