Improvements on fpv signal

[lipefsa]

I just bought an XK X260, which is much like the WLToys V686G and i wanna know if putting an Cloverleaf antenna in the transmitter (LCD screen) will improve the signal of the FPV because i fly around trees and buildings. And if the CL helps, what type is the right one: SMA or RP-SMA ?
I can't see in the photos what the right fit would be.

Take off the existing antenna and look at it.

Mine is coming, it does not arrived yet.
I want to buy the antenna soon because it will come from china so it will take a long time, I want to anticipate.
