Yes, the antenna provides a number of options, but drilling a hole in the roof to both pass the cables and secure the antenna was the obvious option. I didn't drill the hole myself as it would have meant purchasing a suitable drill/holecutter for one-off use and drilling in a moderately congested area in order for cables to arrive inside locker. I was having other work done anyway, so just added that to the list. May have cost a little more than buying the kit to do it myself, but I also purchased peace of mind!
