About a year ago I added the Dish 500, and the installer installed an adaptor and another dual LNB and switch. Although the system works ok, the installation was so messy and unprofessional that I actually considered switching to Direct TV. I like Dish Network Programming and I'm now thinking about cleaning up the mess, installing a twin LNB and eliminate the switches. I'm also considering replacing the co-ax with quad shielded cable. I plan to order the LNB with a dish and use the second dish at a later date to pick up the HDTV satellite. What are your thoughts on this? Can I use one of the dual LNB's to pick up HDTV? All comments would be appreciatd.
