If you're using a SWM, you don't need the HD version, BUT... do not use the flat cable on a patio door or anywhere the flat cable is going to sustain damage, because the power inserter will be pumping lots of DC power through it and it could potentially be a fire hazard. Go through a window, and try to use the window as little as possible and be gentle on the cable.

I don't do an install that requires flat cables on a patio door, because the customer (or their friends/family/guests) always slam the door and damage the flat cable, causing endless service calls.

Power is the reason; sat coax not only passes RF signal, but also DC power. Most solutions that would require power on the outside cause the same problems as having the cable; it's easier to drill.

Drill anyway, and either repair the hole yourself or pay out of the deposit for it to be repaired when you leave. That's what most tenants do. They won't through you out of the place for a (sealed) hole in the wall.
