OTA Antenna installation question on 921

[musicmaker2020]

I have a question. I have read about the 921 and combining the signal of an OTA antenna into the signal of the Dish but it seems not many people are doing that from my readings of several pages.

BTW I dont have a 921 yet but I have been eyeballing an HDTV for the holiday season. Since I dont have one please dont beat me with the you should know this from reading stick :lol:

First off, what do I need to do it and second are there any pros and cons? For example I would like to know how everyone's experiences with Indoor vs Outdoor HD antennas have faired.

Thanks a million!

You can share a cable between the satellite feed and the OTA antenna using diplexers.

The search button is your friend.

I tried many many indoor antenna combinations and locations. I think most everyone would tell you to go ahead and invest in a high-quality outdoor mast and one or more good antennas. At least then you'll know that your poor antenna isn't what's causing any problems that appear...

antennaweb.org is a must.

Does anyone have recommendations or experience with a dipexer that will combine the satellite feed and OTA antenna? Do these devices require a power source?

How do the diplexer's work with the 2 feeds required for the 921? I assume that somehow both connections into the 921 must have the OTA signal.

HotRod,

What exactly are you trying to accomplish? With more specifics we may be able to help. FYI the 921 has an OTA tuner and an OTA antenna input that is separate from the 2 SAT feeds, there is no need to combine OTA signals with the SAT inputs. Diplexers are typically used to 'share' the cable run from the dish with an OTA antenna, eliminating the need for two cables (or 3 rather, in the case of the 921). If you are only trying to get your antenna feed to the 921, you can diplex the signal on one of the two SAT feeds, then split it off and connect it to the antenna input at the back of the 921. Diplexers do require power, but many will pull power from the Satellite receiver, so they do not have to be plugged in to a 110 receptical. I use a TERK 42 with built in diplexers to provide the VHF HD signal for the local OTA HD CBS affiliate. I use another antenna for the UHF HD signals - in my experience, the TERK UHF HD signals suffer greatly from multipath. I combine the signals from the two antennas (via a VHF/UHF combiner) prior to connecting to the 921 antenna input.
