8. TROUBLESHOOTING 
 

a.  Ensure you are using quality multiple shielded cables with quality radial or 

compression F-connectors. 

 
b.  Ensure the F-connector’s center conductor is making solid contact with the 

CTA-30RK-550’s Input and Output ports, and the appropriate headend combiner and 
RF distribution network connectors. 

 

c.  When taking measurements it is always best to use a quality signal level meter.    

System level measurements should be taken from the CTA-30RK-550’s Output port.  
For field maintenance, the CTA-30RK-550’s Test port may be used.  However, note 
that port is padded down -30dB and the 30dB must be added back in when determining 
system level settings and output.
