Mast head amp interferes with Austar reception.

[L.A.T.]

Neighbour has Austar from a dish and free-to-air digital from a fairly new
antenna, via a mast-head amp.
Both signals go to the VCR and thence to the digital T.V.
The free-to-air picture is excellent and the Austar picture is snowy. Very
snowy.
If the free-to-air antenna s unplugged from the VCR, or if the power
plug-pack for the mast-head amp is unplugged from the wall, the Austar
picture becomes excellent. The free-to-air picture, of course, is then
non-existent.
Could the mast-head amp or its plug-pack be causing some interference to the
Austar signal but not to the free-to-air signal?
I don't know why the antennae are connected to the VCR. That is how Austar
set it up.

The power for the masthead amp goes up the coax. Somewhere there will be

a blocking connection, if the VCR is connected on the wrong side of this
connection then it will have the masthead amp power across it's input.
that could be the cause, I inherited such a situation in a house I once
bought.

sounds like you need to set the austar satellite decoder output on a different
UHF channel. contact austar and they'll send a tech (or possibly give you the
code to access the satellite decoder settings.)

Else if the VCR supports software source selection use RCA cables to
connect the set-top box to the VCR

Thank you for your responses.

The snow all but vanished this morning, and then returned an hour later.
Austar will look into it.
