Thanks for the info @Kyle Communications.
I know it has been a couple of years since your post. I'm wondering if you had any issues with impedance mismatch.
I was assuming that coax in the board was for RF testing and coulnd't actualy radiate from it.
Did you need to isolate the board antenna as well ?
I'm thinking about replacing or removing the battery cells so I can actually fit the connector inside the case. Any help appreciated.
