For this example, a simple wire twisted in the antenna hole will do a great job for testing.
'''Please wait before soldering the wire inside the antenna hole!'''.
The antenna hole can be populated with:
* a simple wire
* a {{pl||µFL SMT antenna connector}} where you could plug various kind of antenna.
* a {{pl||PCB SMA Connector}} where you could plus various kind of antenna.
A µFl connector (also named uFl) is locking to this:

== The Emitter ==
We will prepare our message emitter, typically stored inside the CanSat can.
This will involve:
* The Feather M0 Express plateform
* One of the RFM69HCW 433 Mhz module
* An wire antenna
To ease the learning, we will also connect the Father
