A7105 module range Devo 7E

I just installed the A7105 module and bound the Devo 7E with a FS-IA6B using ibus.

I'm using the module XL7105-D03 which does include the PA correct? Hence I need to add that to the hardware.ini file.

I chopped the end connector from this antenna and soldered the center wire to the A7105 and shielded portion to the sides.

I'm just curious what kind of range I can expect without adding an external antenna.

Thanks.

It should have an integrated PA, read here

As a noob, what would be the best method to test the range with this current setup?
