Recently my fiancé and I had moved into a new home and got starlink from previous owners. The previous owners had a weird set up where they had the cable run from dish to garage with router inside, then they ran an ethernet cable from the unattached garage into the house on the opposite side of where we want our office to be.

We recently bought a 300ft cable that i could easily run from the dish all the way to the office but after reading some things online im scared there wont be enough power to move the dish and possiblities of frying connections.

Should I try to install this cable? or am I better off making a waterproof box for the router and running ethernet cable from waterproof box to my house ?
