Saw this while I was trying to figure out how to use an IPad with my HS720E. Great idea! Ordered one on Amazon and $19 and 2 days later. I had it in hand. I mounted it on the two handles as you did, but on top of the legs, It works great. Thanks for this! I'm not sure if I'm going to try the antenna swap just yet, The stock antenna seems to work in all situations so far. Keep tinkering on these, I appreciate your ideas.
