bit error rate help needed

[slimthug]

i cannot seem to get down my (ber) bit error rate it is always about 160000-5000 even though my (snr) is always about 91 and (agg) is about 41 i tried moving the antenna and it doesn't work the ber is still to high i would lik some help if possible.there are no trees in the way and no high wind.

Is your picture breaking up?

As rolfw has suggested, if your picture is OK then stop worrying.

If your picture is breaking up, then it may be time to check your alignment and LNB. Since signals in general are at theiur weakest at this time of year, I change more LNBs between June and August than I do for the whole of the rest of the year.

 

[slimthug]

yes it is breaking up

 

[billnot]

Before blaming the Dreambox, check the rest of your installation. In Europe at least, this is the time of year when any shortcomings in dish alignment or LNB sensitivity make themselves felt.

 

[slimthug]

i replace the lnb cable and the same problem can it be the antenna

 

[rolfw]

Check the Skew/rotation of the LNB as well.

 

[slimthug]

what is that?

 

[slimthug]

the box was showing good about a month ago and now it just breaking up with squares even tho the snr is 90. Sometimes it just stick and say switch service could not be found but i does just change the channel and that goes away.

 

[slimthug]

don't worry about me i'll find something to fix it so don't reply anymore

 

[billnot]

The skew is the angle that the LNB is fixed at relative to vertical. In other words, it doesn't usually point straight down, but needs to be twisted an an angle which will depend on where you are and which satellite you're pointed at. Sometimes it can be very critical (i.e. for pulling in Astra 2A and 2B north beam channels which have adjacent and very much stronger south beam transponders).

According to those stats your signal level is only 41% which is a little low. You sure your all aligned correctly?
