Cold weather signal loss

[Butcha]

When the weather gets below 5 degrees, I lose the satellite signal. When it warms up to 10-15 degrees everything returns to normal. What could be the problem? LNB?

It's the LNB affected by the extreme cold. Same thing happens with extreme heat

Could be the center wire in the cable shrinks back away from the connection in cold weather.

That would be some incredible shrinkage.

Back in the day they had a batch of bad Twin LNBs that brand new out of the box would lose signal on the first warm day. Replaced at least a hundred of them.

Not really, if the connection is tenuous extreme cold can shrink the center wire enough to pull it back from the connector. Make sure your stingers are adequate.

I know of one stinger which definitely shrinks during extreme cold.

I just posted the same thing and then deleted it because you beat me to it.

I live in Minnesota and I have the exact same issue on the satellite dish mounted up on my roof, but it has to get down to below zero. Once the temp falls below -10 or more, I lose signal. If you look at the signal strength screen, it will jump back and forth from 79 to 0, no in between. The LNB up on my roof is a Hybrid and feeds my Hopper 3 and 2 Joey 3s. I know it is not the Hopper 3 as I used to have a Wally connected to it and it did the same thing.

I have a second dish mounted on the side of my deck that has a DPP LNB and this feeds my Wally. It never loses signal even when the temp falls to -20 with wind chills to -40.

Generally sat electronics work better in cold, not worse. These described issues of sudden unexplained loss in cold sound exactly like the postulated too-short coax center conductor- physical contraction of circuit elements. Possibly something in the LNBF could be contacting and breaking circuit.
