It is possible but not very likely, most forms of home Internet connections use RF (radio-frequency) signals to transmit the data, regardless of whether that’s over a wire or over the air. This is true for DSL, cable, and any currently-popular form of wireless ISP. The only major exception to this is fiber-optic ISPs, which use light signals instead of RF signals (but even those could potentially have RF equipment in the transceivers, that is, in the modem.)
Additionally, home networks use RF signals to transmit information (i.e. Wi-Fi, Bluetooth, and even wired Ethernet).
I have read that some HAM radio operators (amateur radio) can be troublesome especially with there large antennas mounted on the side of houses etc. , but never read anything regarding satellite dishes etc. 
You will have to unplug satellite dish and try a test to see if any CRC’s start increasing ?
