New LoPy4 user - do I need an antenna if not using LoRa code?

[dws]

I'm about to fire up a new LoPy, just to get familiar with the device, and won't be using any LoRA libraries yet. I'm assuming it's safe to NOT attach an antenna. Is that correct? thanks.

thanks! i didn't want to damage the radio unit.

@dws Yes. You only need an antenna if you use LoRa.
