questions about jamming satellite TV signals -- sister's bus

Guest
I'm hoping someone here can help with information about jamming satellite
TV reception on a particular dish. My sister runs a small bar /
restaurant and we believe her satellite receiver has been jammed during
key sporting events by a competing business. I am trying to discover 1)
how difficult or easy it is for an individual to jam signals to a
particular dish; 2) is there any way to detect the jamming while it's
happening, or after; and 3) is there any way to shield a satellite dish
from this kind of interference. Thanks in advance for any help or
guidance anyone can provide!

un-cracked.

Possible, but far from trivial, unless the jammer has access to the feed cable.

Not after, but comparison with signal from a signal being received on a dish further away should
identify any problem local to a particular dish

You need to identify the source and nature of the interference, If it really is an interfering
signal being directed at the dish then relocating and/or shielding the dish would probably be
feasible, but you do need to know what you're dealing with.

Should not be impossible but needs special knowledge and the antenna
ponted your way will look suspicious. Look for a dish with the head
higher, not lower, than the dish.

I suppose that a field strength meter shoudl show an increase because of
the extra signal. These are inexpensive.

Probably only moving it. Maybe move it out of the way and tunnel the
signal in over the good old internet (as a backup channel only perhaps)?

Could be as simple as running a spark gap nearby.

If the dish is pointing nominally upwards you could build a "fence" of
hardware cloth around it.

Is your sister's system "legal". If not it could be a contraband
decoding card is inadequate to handling the encryption during "key
sporting events".

I love to cook with wine. Sometimes I even put it in the food.

Are you sure it wasn't just a pay per view event? What did the screen look
like?

A wet blanket over the dish might be enough to mess up the signal. With our
old system a well positioned lawn sprinkler would have been enough to cause
some noise.

I don't know anything directly, but I've seen a card programmer driven
by a PC.

I have seen these years ago, on the series 9 cards. But 10 onwards has never
been broken, at least not publicly.
