When OTA is toggled on, will both D* feeds to the box have to have OTA? In other words, pre-HR20 I had an attenna in my attic that goes into a diplexer along with a feed from the satellite. The signals were separated before they went into the box. When I got the HR20, the installer ran a second feed off the satellite that goes into my HR20, but this feed never goes through a diplexer. When OTA comes on-line will I have to climb into the attic split the OTA signal and run it along with my 2nd satellite feed into a diplexer to be able to fully use the HR20?
