Channel Mapping.

[Clinton Fields]

I had an e-mail forwarded to me from someone that needed help with correcting their channel mapping problem.

First I want to let that person know that I had the same problem you had when I first got my system.

It was confusing me because it was only happening on one receiver. My BravoHD was mapped to Staz. I had diplexers on all boxes, so I thought the one box was having a problem. After two days of calling VOOM, I decided to take the diplexer off the one receiver and low and behold, problem fixed. The problem it seems comes from the length of the run to your receiver and the low power out put of the receiver. The VOOM receiver puts out less power to the LNBs than Directv and Dish so long runs are a problem especially when you throw a diplexer in the mix.

Keep diplexers off when you run is more than 75 feet.

Having your diplexer off of your receiver can cause problems. You are correct about taking it off though, it has been my experience that the signal strength goes up when it is off.

I would not suggest taking it off though, ive seen it cause alot of problems.

I have had mine off for several weeks now and have had no problems. You do not need the diplexer. The diplexer is only needed to combine the OTA signal with the SAT signal. If you want to run two lines, there is no need for the diplexer.
