if you think the lnb is switched by ac voltage I think you are the one
with
a problem not me.....go away


No Mains is ac. If you have leakage it is normally capacitive. DC does
not pass through capacitors.

Capacitors in fact are used to block DC and pass the ac component.

You may have a few class C amps that use this feature.

Now this is a difficult concept, so stay with it.

Your LNB will require a Voltage of around 18V DC.

Between the braid and inner, you will measure 18V DC.

The 18V DC can be present on a cable that is 70V ac or more above
ground.

Grabbing a humble spud would enable someone with a brain cell to
identify the polarity and where the ac component was introduced.

Do you go on air at all?

Does the nice man at the shop show you how to tune a wireless in?

you are a sicko ......dead simple each receiver is providing the voltage to
the lnb and there is a voltage on the outer of the F plugs at the lnb so
must be the lnb that is doing it and giving no horizontal signals to either
receiver....no?...and you know where you can stuff your potatoes....
