Which range extender?

[KnightSpeed]

I just gained the phantom 3 4k. Was all set to buy Drone world's 4 mile range extender and was crushed to find out it's for adv And pro Only. Shame on you Drone world and shame on Dji for not putting light bridge in all models! Since that option is out please anyone and everyone tell me what my next best option is. I have seen elitlite, blueproton, dbs, the circular polerized, etc. I want a braggable difference and not just like a mile. Best bet?

Just wondering. Is the alfa a simple install. Do I only need 1?
