Warning! 

 

Rough handling during the Installation of the coax cables may create the possibility for 
open or short circuits within the coax and connectors.  

Do not attempt to apply DC 

power until all cables have been checked for continuity and short circuits with an 
ohmmeter.

 A short circuit in the main coax will cause the protective fuse in the RSM-

2000 to fail.   

 

Do not attempt to connect or disconnect the main RF cable from the ARA antenna 
while the power is on.

  Although the power supply is rated for continuous heavy duty 

and is current limited at 1000 ma, it is possible to induce failure of the fuse in the RSM-
2000 unit if the center conductor of a connector on the main RF cable momentarily 
touches a case or another grounded component. Failure of the fuse will render the ARA 
antenna totally inoperative until the fuse is replaced.  In this event, use a Radio Shack 
(or equivalent) P/N 279-1062, 0.75 A, slow-blow, 5X20 mm, GMA type.  

 
 
 

Operation - 

 
Once the ARA antenna system has been installed and the cables checked, the system can be powered 
up.  Apply power to the radio system and set the band and frequency to a location where signals will be 
found in your time zone.  Plug in the ARA power supply and you should immediately hear signals loud 
and clear.  If this is not the case please refer to the troubleshooting section and contact your local 
distributor for addition service support.  
 
A key feature of the ARA products is that they are broadband and require no tuning.  After successful 
installation, you can count on enjoying continual high performance for years and years without ever 
having to adjust your ARA antenna system.  We do advise that you make a routine annual inspection of 
the external connections to detect any serious degradation in the connections or cabling.  
 
 

Troubleshooting - 

 
The following information is provided as suggestions to be used in the event that an ARA does not appear 
to be performing in a normal manner.  A good "go - no go" performance test is to disconnect the power 
supply from the wall while listening to the signals on the radio. You should hear a major increase in signal 
level when the power is reapplied to the antenna. If you do not hear any increase in noise or signal level 
please use the following procedure as a guideline to help you to troubleshoot your system.
