Trouble with OTA antenna using diplexers

[reservoirreb]

Hello.

I am new to this forum, so bear with me.

I am having an issue with an OTA antenna I am using with a Dish Network HD/DVR receiver. Actually, It's not really the receiver that is the issue, for this is also happening when I use the ATSC tuner built in to my Samsung 40" LCD.

What happens is this. When I use diplexers on with the OTA antenna (of course with my satellite signal) my signal from the antenna basically disappears. If I bypass the diplexers completely, I get a signal around 80% on around 13 channels. This is without even having the antenna outside, but rather inside my house. However, when I use the diplexers my signal almost goes non-existent.

I even tried using the diplexers 20 feet apart, just for troubleshooting purposes and the signal was barely visible.

Am I doing something wrong, or do diplexers really degrade the signal from my OTA antenna this much? My satellite signal comes in with no loss at all.

I just don't see how diplexers could make a signal drop that much over 20 feet.

Any help or advice would be appreciated.

Here is some more information that may help:
