When you say "signal degrades" 10dB what do you mean?  Where are you measuring 
this "degredation" and what are you mesuring it with?

Do you have a spectrum analyzer?  If not, rent one and look at your signal from 
a mile away when everything is working properly.  When the problem occurres, 
look at your signal from the same location.
