It's all dependent on the area where you fly, your PS3 is dependent on a wifi and electrical interference free area coupled with your aiming technique. You can try using a simple windsurfer which I have used to great effect before you drop into the world of aftermarket antennas. They cost about $15 and concentrate your signal forward more so than the omnidirectional standard set up. Maybe try that to see if you are happy with that set up and work your way up. I had success with this and using height and a good aiming technique had me out to 1800 mtrs with a good signal, much better results from many on this forum, but good enough for me. You can adjust your channel in the settings to find an interference free channel and reduce your bitrate transmission when filming to give you less grief and better video strength. Trial and error.
