As Rafa Scales the Roof, he finds the cables bundled into a PVC pipe on the roof. The pipe goes across the roof, ending at a laser repeater device pointed to the east, somewhere in the direction of the Robertson Blvd. Checking all the roofs for the receiver would be very time-consuming and defiantly not doable half a day, you are left with.
These things point in a very specific direction though, no? Can't he use something (let's say, his rifle) and align it with the laser pointer to see where it's pointing?
That's the way you got the area approximattly right. laser beam must have a exact receiver, but over long distances it's hard to tell exact

The distance is over 15 Km, no way you can see where exactly it is

but as all the rooms seem to be bugged the owner should know something, just hope the manager does too
