Hi this is Edwin on August 30 2002 there was a Dish Network Satellite TV installation using two satellite dishes with y bracket each one. One of the satellite dishes were dish 500 with dishpro quad lnb that's not dishpro plus quad lnb I'm having a hard time identifying the second dish that contains a y bracket with a single rg6 cable connected. Also I'm not sure if there was Dish Network Dishpro 44 switch not Dish Network Dishpro plus 44 switch in 2002 I would like to also find out when dpp was introduced not dp. Can you help me find out what dish network lnb was used? Thanks.
