TROUBLESHOOTING 
 
All cables should be carefully checked for “shorts” and “opens.” 
If cables are O.K. it may be necessary to use a spectrum analyzer to examine the 
signal environment in which the BDA is operating. The existence of strong analog 
signals within the frequency bands can cause problems particularly on the downlink. 
In some cases additional filtering might be required to reject these unwanted signals. 
There may be some cases where the interference from outside signals is so great 
that they can not be filtered or otherwise reduced or eliminated without expensive 
and possibly prohibitive measures. In these cases it may not be practical to use the 
BDA for providing coverage at these sites.
