Dear Dave, Jese, It was the connection issue. The pin inside was too long so that I snapped the connection point. It works now! Thanks!

Thanks Dave. I've tried the external antenna. It works on the RX but not the TX. With the same setting and self made antenna, the TX just drop from -35dbm to -70dbm comparing with the original one in 1 meter range. And also, I didn't see any circuit that allows G3 using dipole antenna, is it really possible?

Hi all, 'I've been following this topic for a while. Just to make sure that where to ground the second antenna? On to the case? and since grounding the antenna is a requirement, is there any possibility to make these puppies a dipole antenna?
