Mkr Wan 1310 no antenna?

I buy 2 mkr lora but without antennas. Can I use like this or I need the antennas?

Best regards
Joao

You need an antenna, do not attempt to operate the LoRa device without an antenna connected.

But in store the product include antenna ( Arduino MKR WAN 1310 — Arduino Official Store ) .
Where is the diference? Why I must have now to buy 2 antennas apart?

I dont know, I am just a volunteer on this public forum, I dont work for 'Arduino'.

If you have issues with what you were sold take it up with whoever sold it to you.

Ok, thanks by the help!
