My 622 was delivered today via UPS. My install date is Feb 21. Can I install this myself and get it activated? I have a 121 superdish as well as a 61.5 dish. Does the 622 come with a seperator? I will need one as it is replacing an 811. Should I wait until the 21st? I'd like to have the installer swing the 61.5 over to 129 when he comes... Any thoughts??
