  Howard,   I  had  alot of  problems with  my  station  getting into  the 
Directv  system.
           All  was resolved  with  toroids .... (  alot of  toroids)
           I ultimately  switched to  cable (  cost alot  less)
             no  toroids  needed  for cable  tv..........

                                     ..............Bill / w2ay
