    It is a Zinwell WB68 (6x8) and it will not behave with diplexers. The new 5LNB layout clobbers some of the OTA TV band.

    Do a search for "diplexing".

    My Mom has an OTA antenna hooked up to her HR-20. Everything is configured just fine, and we can watch the OTA channels. The guide is populated and we can see what is on our PBS-HD, CBS-HD channels, etc.

    However, Searching does not work. Here in Albuquerque our CBS station is owned by LIN, which means you cannot get the HD feed any way except OTA. If I do a search for "NFL Football" it finds all the games on all the satellite channels, but does not find the games on our CBS station, even though they do show up in the guide.

    Did I miss a step setting up the antenna channels?

    Thanks,

    John

    Man . . . I just upgraded to an HR20-700S a couple of weeks ago and was hoping to get an HD antenna connected relatively easily. It sounds like I'll need to mount one on the roof and run a dedicated line . . . but with my farthest DT station only being 15 miles away does anyone think an indoor antenna would work?


    Thanks.

    It very likely will. I'm running a -100 with the small whip antenna that should mount to the input for the RF remote function (the 700's antenna is internal, while the 100 requires an external antenna) attached to my OTA input and am getting my OTA stations just fine. Mine are all about 12 miles away, and if you end up putting a real OTA antenna on yours, you'll probably get everything just fine. My setup is in my 1st floor living room, and we've got plenty of trees.

    I bought a Philips Mant940 and it picked up 25 or so stations with signal strengths ranging from 67%-83% with the antenna sitting on my computer desk on the back end of my house (about as far away from the signals as I can get).

    The stations I can get are actually pretty decent. I'll probably move it to the outside and see how that improves things. The antenna came with a small signal booster, but I might see how a different can improve things.

    :D


    This forum is full of great information. Thanks.

    So, do searched return results on OTA channels for everyone else, or is this a known bug?

    Thanks,

    That's kinda like me asking you what my view of the mountains is like.

    Without knowing your terrain and whether the stations are all broadcasting from one place or many, it is exceedingly difficult to tell.

    If http://www.antennaweb.org says it doesn't take much of antenna, you might be okay with an indoor antenna (assuming you don't place it in a below grade basement). Remember to select "Show Digital Stations only" when you get the station listing.

    All ready taken care of . . . and it didn't take much of an antenna. :D

    Any suggstions on the best way to hanlde multipath on the HR20 with a weak/moderate signal? I am only ~20 miles from Atlanta, but have a 600-700 ft mountain/hill in the line of site about 1-2 miles away. I have a 4228 antenna on the roof and added a 7777 pre amp but I still get variable signals on some channels. I suspect multipath and less than optimum signal to noise ratio. My Sammy DLP set does a better job of handling the signal than does the HR20's tuner. Any suggestion on how to help the HR20 out? Variable attenuator perhaps?

    You could try a CM 3022. They have a narrower beam width and greater gain than the 4228, but you might have a problem with stations beyond a 30 degree beam width. If that's a problem, you could use them both pointed in different directions(with separate feed lines only!) and switch back and forth with one of those little, inexpensive 2-way slide switches you can still buy at Radio Shack. They even carry IR remote control coax switches. I tested them both, and the insertion loss is negligible.

    Be careful with those antenna amplifiers. They are subject to "front end overload" from nearby transmitters, and the result is NO ATSC picture at all on only certain channels.

    All that being said, the HR20's have a set of poor OTA tuners, and many people have problems with certain channels that any H20-600 or new TV has no problem with. See also this thread: Trouble With OTA Reception - HR20-700

    I bought the CM3022 and CM7777 and have had great results 57 miles out from Chicago.

    The link you gave to solid signal is the one to use.

    I see from a December '06 post that the ability to manually add OTA channels to the HR20 is something that may or may not be added in a software update - does anyone know the correct method to let Directv know that there's a mistake in the channels listed for my zip? They show the guide programming on 29-1 that should appear on 29-2, but don't show 29-2 at all.

    **edit** nevermind I found thread #85879


    Thanks.
