hi,

You can replace a new antenna by yourself.

Hi, I have done this modification on my HT-M00.
I solder an SMA coax cable and glued with epoxy on the case. I use the positive pin from the original antenna and use the nearest ground pin.
On Thingiverse I print this antenna jig LoRa antenna jog and made my own antenna. I use a NanoVNA to tune the antenna at 868MHz.
