LilyGo T-Beam v1.1 setup Questions

Hello, I’m a beginner at LoRa and was wondering if I need a Bluetooth and GPS antenna for the LilyGo T-Beam or if it is good on its own?

I would like to use to use the GPS capability of the T-Beam for ATAK.

ATAK uses the GPS in the EUD.

As far as I know it has both already. Radio antenna must be attached by you else fries the chip.

Okay, thanks for the clarification.
