Diplexing through an AT-9?

[johnml]

If I had known that the diplexer would not work (eventually), I would not have even bothered with the new dish. I guess I should have done more research before having the new dish installed.

I just had the new dish installed yesterday and my OTA antenna inst working - it is the multi-switch. Directv is coming out next week to run a separate line for me since the installer should have done it while he was here. Even the CSR knew what the problem was when i mentioned it.
