My parents are on my 2nd DISH account and they have the 722k and they are at a "moved" service address. Now we use a diplexer to turn the clip on antenna to do both sat and ota. It has worked well for me for years I have the same set up at my house on a 2nd sat dish running to my turned off 211k to power it for just ota .
But my parents have a two story home on either side of them and a huge tree in the back yard of the house directly across from the sat dish. I ended up going with eastern arc lnb and repointed and reaimed the dish so they get great signals on their satellite channels, with no reception problems that were caused using western arc and that damn tree in the neighbors yard. But here is the rub. They get comparable strengths as mine on their ota signal on ABC, NBC, and FOX. But of course they want to watch their local CBS station for their news. That channel comes in at 70 - 75 strength and often crashes and causes break ups and no channel. I get it around 100 strength at my house down the road.
I think that one channel is being blocked due to the 2 story houses and the huge tree. Except that the same signal is split to their tv as well. The hd Phillips tv is doing just fine with no break ups on any channel. My dad has often watched it instead of the sat receiver due to the break ups. I even replaced the ota module in the 722k and it made no difference. I repointed the Terk 44 omni directional clip on antenna and it can get better signal on CBS ,but they lose the Fox station and the strengths on the ABC and NBC station will go way down to around 75 - 80 strength. Mean while the tv never loses signal on the ota tuner built in . So I have to imagine that the older 722k ota module is not as good as it should be. It might be just older technology that doesn't work as well as the tuner in the newer tv.
I have a new antenna coming Tuesday that is an real stand alone antenna and a dedicated line run so we can do ota on its own with out the diplexer thing. I hope this will fix the problem. I also have a 4 tuner Tivo coming for just ota- got it from Best Buy using my reward credits . If it works with the Tivo and doesn't lose the CBS station ,they can just use the Tivo for their own local stations and keep the Houston stations for the news they like to hear from the big city. I used to live in Houston for a year back in the early 90s and I hated watching their news; due to the murders/robberies that were so prevalent. I tried to get them to upgrade to the Hopper and get their own locals and my dad say NO WAY for the $15.00 dvr fee. So if this doesn't work they are just out of luck.
