Hi ashfaq1959.
RadarBox should work fine - it comes with an aerial that will pick up signals from about 200 miles if it has a clear, unobstructed view - position, and height, are all-important. It's very easy to set up, very portable, and will pick up most of the international airliner flights within range - there may also be local flights that it can pick up, depending on the equipment fitted to the aircraft.
Hope that helps.
