well just a subtle suggestion to any indian airport officials...perhaps you should try not pulicising the location of your ILS outer marker equipment etc so vividly?
I was in Delhi in april and,driving down a main road near the embassy district was a huge garishly painted billboard over a hut proudly proclaiming "runway outer marker".Maybe try keeping it hush-hush where the million dollar hardware is kept & thats part of your problem solved?
