sorry, re-read that. your talking between the block and LNB. yea, if you just undo the latch or the two screws holding the LNB in, cut the zip tie, pull the LNB off, and do the whole thing in reverse with the new cable (or when your done) you'll be fine. just check all the bolts on the back of the reflector to make sure they're tight first. most times those things are put together with an impact driver so if you bump it you're not going to do anything to it.
