1. Huawei would not have made the decision on where to locate the mast. BTEE would have made that decision.
2. If the location is "Top Secret", BTEE wouldn't know about it, and would have made the decision purely based on a review of their coverage map.
3. If BTEE are aiming for (semi) decent coverage, and Huawei are their preferred supplier of masts, it is pretty much inevitable that this would happen.
