I have my n5.2 on a grass beach and i use four screw in anchors from menards. I put one at each corner of the tramp and this has held up even with wind gusts to 60 mph. BUT...I had an h16 that wasn't so lucky. I had it tied down and it managed to blow forty yards away after my mast speared through a little Saturn car. Funny thing was, the h16 sitting next to mine was still there even though it wasn't tied down. But it didn't have a tramp. Food for thought.
