AM21 OTA Module, Diplexers, and DECA and MRV ? ? ?

Is it possible all this can work together? Just got installed with the whole house DVR set up and the DECA connection to the internet. One thing I had with Dish that I kind of miss was OTA reception using an antenna in the attic and then I used diplexers to backfeed the antenna signal down the main cable to the receiver so I didn't have to run extra cable to an antenna.

I'm wondering if I can do that now or if the diplexers could interfere with MRV and the DECA setup. My hunch is that it would be too much mixed together in the coax and I don't know if the internet and mult-room frequencies operate in the same badwidth as the OTA signal would. If they did, it would certainly not work. I'm just curoius if anyone here knows.

I'm new to Directv but I know that diplexers don't work with DECA installations because like you said, OTA operates in the same bandwith as DECA.

Don't do it. You would be better off dropping another line for OTA.

Yep, that's what I'm going to do. Another independent line. Thanks for the feedback though. It's nice to know it's necessary before going to the trouble!

Two good reasons to use a separate line.
1) No signal loss due to insertion loss or splitters.
2) The AM21 can share the recordings to other TVs via MRV and thus only the AM21 needs to be connected. (Unless you plan to feed a TV with an ATSC tuner)
