I have swm 5LNB my question do I need 29v or 21v insert?? I have 21v that came with swm 3LNB which upgraded to swm 5LNB some local channels keep losing signals at 7M in the afternoon could that be possible with the power not supplying correctly??

Thank You all

A swm lnb needs only the 21 volt power inserter, but can use the 29 volt model. The 29 volt one is used on the swm switches. Test it with a VOM when you are losing the channels. If you have a particularly long run to the dish, you may need to switch to the 29 volt one. Check all of your connections, and make sure there is a terminator on any open ports of a splitter. I'd be more suspicious of the lnb.

What are your satellite readings for signal strength on the 101, 110, 119, 99ca, 103ca and 103cb ?

It could be an alignment issue, but wouldn't that most likely be a problem all of the time?

Not necessarily. He could be in an area that is getting afternoon clouds and cutting a little bit down on a marginally aligned dish.

I am getting above 90 on signal strength on all birds it just that at I can watch the local channels no problem until 7m and lose signal only on those local channel and their is not a cloud around the sky. I am guessing it could be the LNB problem???

Check your connectors, specially those outside

Is this happening only on the HD local channels or both the HD and SD local channels? They come from different satellites in most cases. Depends on your zip code.

If you're not losing CONUS channels on the same bird it probably isn't the LNB.

If you were losing the CONUS channels as well, I'd be looking for condensation on the feed horn lens.

What error message (please be precise) are you getting when you attempt to view local channels after 19:00?

The local are HD channels that I am losing and the error code is 771 Searching for Satellite signal just as it hit 7:00 PM???

Are there any other channels that go away at 7:00pm? Have you run the signal strengths before and after as jimmie57 suggested.

If it is always at 7:00pm, do you have any recordings set for that time slot?

What your experiencing may appear rather extraordinary but their could be some pretty ordinary reasons (like too many tuners on a SWiM LNB).

The only local HD channels goes missing all others are fine and yes I have run the signal strengths are above 90 level also I don't have any PVR so no recording.
