Scott, 10:1 vswr indicates a GROSS mismatch. This can happen when there is  
a short circuit or open circuit between the coax and gamma match.
 
Ian had a good suggestion about the N connector. If you connect a dummy  
load to the antenna connector, you should be able to measure the load  
resistance at the gamma match connection with your VOM/DVM. Better yet, connect  
the dummy load to the shack end of the coax and check the whole system.
 
Happy hunting!
