Default Combining post Dish receiver signals and over the air signals

I have a Dish VIP 722 DVR receiver which does not allow over the air signals to go to TV2. I used a splitter in reverse to combine the signal coming from the Dish receiver and my over the air antenna. The Dish is set to channel 59. The problem is that the Dish signals are sometimes snowy but the over the air signals are clear. What did I do wrong and how can I fix it?

Thanks

You need what is called a Diplexer, this allows the two signals to be combined then separated without too much signal loss.

You need two, one outside to combine the satellite signal with the OTA signal, then one at the TV/Sat receiver to split them out.

A normal TV or CATV splitter can't do this as it can't handle the higher frequency's used by the Dish VIP722, the Dish receiver uses band stacking to get all the satellite transponders down one coax at once, this uses a much higher frequency the the standard splitter can handle.

If you go looking for a diplexer make sure it can go to at least 2.5 to 3 GHz.

This will not work,he is talking about the TV2 out of the 722 to TV and OTA signal. only way is use a AB switch so you can select 722 out or ant

OK...In that case then he needs one of these hummers.

But if the signal from the 722 is fuzzy then it could be interference from one of the OTA signals, try changing the output channel on the 722 to one further away from any OTA UHF channel (higher or lower) that may be the strongest one at your area, this is a common problem.

To find out what OTA channel is too close in to the 722 output go to TVfool.com and do a report, this will give the stations power level at your location, if one is too close to TV channel 59's frequency then try one further away. (up or down the band)
