The commercial jammers referred to in an earlier post advertise 10 to 45m or so range, with significant power levels and battery life measured in a few hours. Considering that these devices are illegal to begin with, I have to assume that these figures are probably optimistic (optimistic advertisement is probably the least of their concern.)
If I were a pilot, I would probably be more worried about the kid playing with his Nintendo in 15A (or his father trying to retrieve his email with his GSM smart phone) during approach than a jammer on the ground.
