Mobula6 Antenna Fix

A little work on the modified Mobula6 antenna because I wasn't getting the range I did when I installed the new antenna.

You mentioned 25mW VTX? Mine actually has smart audio and 3 power settings (I think 25, 100 and 200mW). Are you sure you only have 25mW?

You are indeed correct, cheers 👍

BB is 3V or 5V？
