Yes as I said earlier, there is nothing on Satellite IF above 2000MHz=20
usually. Sat IF is 950MHz to 2100MHz.
The actual signal picked up by Dish is 10.7 GHz to 12.6Ghz band.

I've heard of interference of WiFi by Microwave, Though I'd wonder about=20

Power is usually a big transformer. So I'm puzzled.
