It is always best to run two lines, one for the Antenna and another for the 
dish. If it were not an amplified antenna you would not have a problem as 
long as both diplexers have dc pass on ONE SIDE ONLY. Your problem is that 
you are trying to use two power supplies on one line. You might try taking 
the antenna amp out of the circuit. However I have always found that all 
problems go away if you just run another line for the Antenna.
