Installer came in was supposed to do a "basic" install. There is a existing Direct dish at my new apartment from a previous customer looks pretty old. I asked the installer to install a NEW LNB due to my concern about the age and harsh heat conditions at my location. He said I didn't need to worry because of a 90 day warranty on the equipment. I wopuld have rather had a NEW LNB installed especially since I paid the 21.95 handling fee for the equipment. Should I be concerned about the longevity of the old LNB ? Can I insist that I get a new one installed? Thanks for the help.
