Default signal disruption

I live in a studio. My Sirius One radio is about 15 feet from a microwave oven. My outdoor antenna is about 15 feet away from microwave oven, but outside the window door which the microwave is near. When the microwave is being used the Sirius signal is interupted. Constantly in and out. It does not bother me since I don't use microwave that much, but I was wondering if anyone else has noticed this. Call me stupid, but any ideas on why this happens ?

My microwave oven does the same thing to an under cabinet FM radio I have near it. Microwaves (the energy that heats things in your microwave oven)are essentially a radio frequency. Microwaves are actually used to transmit data and voice wirelessly, a lot of telcos do this. You wouldn't want to be near the transmitter, it can cause serious burns if you're really close to the transmitter. The reason those don't cause interference is because microwave towers are directional.

Microwave ovens, on the other hand, have RF bouncing in all directions in order to hit whatever your trying to heat on as many different points as possible.

When you turn your microwave oven on it emits a ton of RF (radio frequency) even outside of the box. Not enough to cook your insides but definitely plenty to disrupt local radio reception. (just in the immediate area) I'm sure some microwaves are better than others at the amount of signal interference they produce, but they all do to some degree.

Next time your cd burner fails to burn a cd,rendering it useless, stick it in the microwave for 20 seconds or so, really cool light show! Microwave ovens can also make a light bulb light up if you put one in there! The energy in the radio waves is enough to induce an electrical current in the metal. Probably not good for your microwave though.

It used to be a problem until i got the antenna up to the roof and 10 bars sat 10 bars terr now the sirius signal overpowers the microwave interference .

Now I understand thanks ...200. Good to know some others have had the problem as well. I maybe able to move my antenna to a different location, but not to worried about it for now. Thanks for the replies.
