There’s a very useful free App that will allow you to judge if there is something in the way of your equipment, look for SatFinder Lite
If yours is an Oyster system and hasn’t been used or updated for a while it will quite likely spin around 3 times, stop and change angle, spin around again, change angle, spin around, change angle, spin around, change angle……….. and so on until it finally finds its starting satellite.
hope that helps, or post what make you’ve got, so you can get other assistance.
