I just had a new DishNet installation done on 09-04-07. Had a !00.2 dish with a 722 and two 411 receivers installed. The installer did not ground the system, he just has the cables from the lnb going straight to the old cable tv wires going to my outlets. The cable tv system wiring is grounded but the dish system is not connected to this in any way. Should the installer have put in a ground block and connected it to the cable ground rod or to a new ground rod ? Also, one of the 411's was having trouble with losing its sat signal. Installer said it was a bad receiver and contacted dishnet to have a new receiver shipped to me. Could the problem with the receiver be caused by the system not being grounded. The 722 and the other 411 are working fine, Should I contact Dishnet and have them come back out and ground the system ? Thanks.
