You need to do a little PD (Problem Determination).

Try another "known good" TV on the aerial feed and try the TV on a "known good" aerial.

If it turns out to be the aerial feed, you need check the cable(s) and all connectors ans the antenna (aerial) itself.

BTW, not sure what this has to do with satellite receivers?
