Something like once every 2 days I cannot watch horizontal SAT channels for about a half day. It says "no signal". During this "no signal" time I get very rarely watchable time. Like 1 minute in an hour. The after this "no signal" time ends there is no issue for about 1-2 days. That was for H.

On the other hand, I never have issues with vertically-polarized TV channels.

What might be the problem?

The 14/18V electrically controlled polarizer is integrated within the LNC and runs thru the coax cable.

Issues may exist with DC supply voltage, polarotor, the co-rotor, the skew alignment, the channel programming or the LNC or very advanced microwave propagation issues with solar angle.
