I purchased two antennas - the Winegard HD7694P (aimed at 230 deg. magnetic) and the Antennas Direct DB4E (aimed at 144 deg. magnetic) as you specified in your original reply to me.....It worked like a champ and I am able to see several channels at very high resolution!

Good.

In your original reply, you mentioned as an option to purchase the Channel Master CM 3412 (or CM 3414). I went ahead and purchased the CM 3412, but I'm not certain how to configure the two incoming coax signals into the CM 3412.

The two coax lines from the two antennas DO NOT go into the CM 3412. The two coax lines go into the UVSJ to combine the signals into one coax line that goes to the splitter.

BUT

I looked at your previous thread and I see that I misunderstood what you were saying. You never said that you were going to split the signal. The only time you mentioned splitter was

He felt that no amplifier was necessary and that I could couple the two coax lines from the antennas into a splitter and send it down one line and into my office.

I have a Tablo DVR so I wanted both signals to be directed into the DVR, then Wi-Fi from the Tablo to my router, then, finally, to my Roku device.

If the combined signals from the UVSJ go directly into the DVR, then you don't NEED a splitter in the first place. My fault for misleading you, and I apologize. Mea culpa.

If the signals from the attic loss are weaker than expected, then add a CM3410 or 3412 between the UVSJ and the DVR:

If the 3412 is near the DVR, then its power supply can be nearby. If the 3412 in in the attic to amplify the signals before they come down the coax, then it can be remotely powered up through the same coax that feeds the signals down.
