Within such a short range such as the confines of the airport perimeter, VHF will not be greatly effected by a "hump" in the runway. There are hundreds of airports around the world where you can't see all the thresholds from one another. I actually think people are more vigilant if there is an obstruction in visibility. Airplanes pull out in front of other airplanes at flat airports on a clear day all the time hump or no hump.
