Best range extender for phantom 4 pro?

[Vtmadmax]

Newbie here! Just wondering what folks have used for a range extender for my DJI phantom four Pro? Not sure why my range is so low, I live in Florida where it’s flat and have a very short range before it tells me out of range territory if there are no obstacles other than trees, should it go the 4.2 miles that they boast on their website? I live in Panama City Beach Florida and have pretty good line of site except for a couple of trees sometimes. Is it possible that there’s so much signal around me that it’s interfering with my drone? Anyways, if someone has any information on extending the range I would mostly appreciate it!
Thank you,
Ron

What kind of range are you getting now? And what's your target?

FYI, flying beyond visual line of sight (BVLOS) isn't legal in the US without FAA approval. It depends on your eyesight, of course, but under ideal conditions, most people can't see a drone clearly once it's more than about half a mile away.
