Phantom 3 standard controller antennas

Ok so I wanted to upgrade my antennas with 12v wifi boosters and I was wondering if I needed one for each antenna cause there are 3 total not sure what each antenna functioned.

The two internal antennas operate on 2.4 ghz and are for receiving video and telemetry. The external antenna operates on 5.8 ghz and is for controlling the drone. I would recommend using a booster on each one for the best results.

I ordered these 9dbi wifi antennas and plan on installing them first and later on down the road install the wifi boosters and dc battery's, from what I research the 9dbi were better for range than any others antenna
