No special tools required.
They will have some coax cables connected to the LNB. Assuming there is no STB at the other end you can either just cut through them or unscrew them from the LNB. Other than that just unbolt everything bracket.
Dishes and the mounting hardware can be a bit heavy so you may want to consider removing the dish and LNB from the bracket first and then and then removing the bracket so as to make two lighter loads.
