Do you hear a noise increase when you power up the preamp? If not, are 
you sure you are getting power to it? Can you hear terrestrial 
repeaters, and does the signal change when you cycle the preamp power?

Check your ins and outs on the preamp to make sure they didn't get 
reversed. Same thing for any diplexer you may be using as a high pass 

More of the obvious...sure you are tracking correctly, and at the right 

I wouldn't suspect any of the cabling or adapters other than one being 
flat out broken. The preamp should easily overcome any shortcomings of 
the cable you've described.
